General questions

What happened with Giga-International.com?
At the beginning of 2013 we replaced our company name "Giga-International" with "Contabo" which is not only considerably shorter, but at the same time even more catchy. The new company name Contabo GmbH is nothing but a continuance of our previous company name. The company as a legal entity remained likewise unchanged as the partners and owners, the staff and - above all - the top quality service level to the benefit of our customers. Since that time we are available for our german customers under Contabo.de and for our international clients by using Contabo.com.

Where do I get my access data?
You will receive your access authorisation from us by e-mail immediately after the account has been set up. This is usually sent to you shortly after you place your order and after we will have received your initial payment.

What payment options are there?
We accept payment by bank transfer, PayPal, Skrill and Western Union. You can use your credit card with either PayPal or Skrill. The first payment after you have submitted your order on our website has to be done manually by you. Please just use the payment information provided to you after the order process. Once you have received your login data you can send your payments using our Contabo customer control panel very comfortable anytime.

How long does setup & domain order take?
We usually set up the domain within a few hours but it may take between 12 and 24 hours before the domain(s) is/are registered. If you would like to transfer an existing domain to us, this normally takes one to three days. (Please note that orders placed using bank transfer as a payment option can only be processed after the first payment has been received).
Since set up is considerably more complex for dedicated servers than for packages, the configuration of a dedicated server can take one to three days.
If you choose the 'Instant Setup' upgrade, you will get your server installed for sure within 12 hours after we will have received your initial payment.

When do I have to pay and what happens if I fall into arrears?
It is important that there is a cover period of five days before the beginning of a new monthly period. If this payment is not made we will suspend access to your server at the beginning of the new monthly period. You will receive an e-mail reminder ten days before the beginning of a new monthly period.
Should you fail to contact us regarding a server for which payment is not covered, data loss cannot be ruled out.

Can I order additional domains for my package/server?
Of course - this is easy and can be done at any time. Please use this link to place your order.

I've received an invoice, but I'm sure I have already transferred the amount stated.
Irrespective of payments made in advance, we are obliged to send an invoice for rendered services. If you have already paid in advance, please regard the invoice as confirmation. This does not apply, of course, if you have been notified about non-payment – in that case, please send your payment immediately. You can view your payment history as well as previous invoices and you can send new PayPal and Skrill transfers in a comfortable way, anytime, using your Contabo customer control panel.

I want to transfer a domain to Contabo
Transferring a domain to us is child's play. During the order process – please compare FAQ How can I order a new domain? – you will have to enter the auth code of your domain. If you do not yet have the auth code available, it is no problem to place the order without the auth code; you can send it separately via e-mail later on. Please ask your current domain provider for the auth code. We require the auth code to start the transfer; without it a transfer is not possible.

Where can I close the account?
You can cancel all of your services in your Contabo customer control panel. Using the „Manage“ button in the menu item „Your services“ you can schedule the termination of any service that you do not longer want to use.

I am interested in more details about the Contabo data center
Contabo operates two high-performance data centers in Munich and Nuremberg for its customers. Further details about our two data centers as well as about our excellent network connection can be found on our website.

I want to contact the bookkeeping department directly
Please feel free to contact our bookkeeping department directly via the e-mail address [email protected].

How long is the support staffed per day?
Our support experts are available via phone at least from 8 a.m. till 11 p.m. (CET) every day - also on public holidays as well as on sundays. Furthermore you can contact us at anytime via our support e-mail address [email protected].

How can I check the current status of your data centers or whether there are service interruptions?
You can inform yourself about the current status of our data centers on the website http://www.contabo-status.com . We are working hard to avoid any kind of interruptions and to ensure that you do not have to face any issues. Should there, however, be some interference in one of our data centers, we will be posting updates about the current status/progress on the aforementioned website.

I want to buy a signed SSL certificate
We can offer a signed SSL certificate at a price of 74.99 EUR. Please keep in mind that the signature of the SSL certificate is always valid for 12 months, this time period will not be automatically extended. You can order an SSL certificate together with your desired product on our website, or you can order it separately at a later date via e-mail to [email protected].

I cannot transfer my domain to Contabo, but I want to use your DNS servers
If you would like to use domains from third party providers, you can register an unlimited number of DNS entries on our name servers free of charge. You can easily create DNS entries in the Contabo customer control panel under the menu item "DNS Zone Management". After the creation of the accordant DNS zone and once our name servers are assigned to your domain at your current domain provider, you can administer your domain in a very comfortable and secure way. Only the current domain provider is able to change the assigned name servers. Thus, you will have to contact the domain provider directly, or alternatively use an administration panel from your domain provider if available.

I want to recommend your products, do I get money for successful promotions?
Yes, for this reason we have started our affiliate program, for more details please have a look at our affiliate site here.

How can I order a new domain?
Before we can register a new domain for you, you will have to place an order on our homepage: http://www.Contabo.com/?show=domains. Here you can also find an up-to-date domain list with the corresponding prices and contract periods.

Enter the domain name without the extension (e.g. without .com) into the text box which you see below the headline “Check domain”. After this, define the extension by ticking the accordant box or by choosing it from the drop-down menu “Further domains”. Continue with “Check availability”. You should receive a green confirmation line that the domain is available. If you receive the information that the domain is already registered, start over again with an unregistered domain. Now, insert your e-mail address, agree to the general terms and conditions by ticking the accordant box, and follow the order process with the button “Register domain”. It is required that you state the exact e-mail address from your first order, which is, in fact, an authorized e-mail address stored in our data base. After this, an e-mail is going to be sent to your address. This e-mail contains a confirmation link that is valid 24 hours. You need to click this link to finish the order. Once we have received your domain order, we will immediately take care of your request.

How can I order a new product as an existing client?
If you already are one of our customers, please also place your order on our website Contabo.com. After choosing a category from the product menu, you can start the order process with any of the “Customize & order” buttons and continue with “Order now” after the product specification. On the next site, you will be requested to enter your customer data amongst others. Choose the option “I am already customer”. You will find this option on the left in the section “Your data”. Now, you only need to enter your contact e-mail address which is stored in our data base, and you should also tick the box „Allow Contabo to use your existing customer account balance...“ - we explicitly recommend to tick the box as it can significantly improve the order process. Complete the order with the buttons “Review and submit order” and “Order bindingly”.

How do I order upgrades for existing products?
You can order upgrades for existing products at any time. Just send an e-mail to [email protected]. We will be pleased to give you advice and help you realizing your plans.

Does my server or webspace at Contabo come with a DDoS Protection?
Yes. All servers and webspace packages in our datacenters are provided with a DDoS Protection by default. Our customers don't have to take any actions in order to benefit from it - the Contabo DDoS Protection is activated for all of our customers automatically and free of charge. We work continuously on further improving so our protection system can repel many different attacks. However, like any other DDoS protection, our protection system cannot provide a guarantee that any DDoS attack imaginable will be repelled. More information about our DDoS Protection can be found here.


Webhosting Package-specific questions

How do I order options (additional web space etc.)?
You can order additional web space, more databases, e-mail addresses etc. by e-mail. For initial registration this may also be carried out using the order form, of course.

Can I change the package?
Yes, you can. This is possible free of charge. In the case of a 'down-grade' change, however, we cannot refund any price differences. When changing a server or changing from a package to a server, you must transfer your data by yourself. The following case is an exception: The administration software cPanel is installed on both servers, which enables automatic account transfer. When upgrading a package, you may still continue to use the old package.

How do I create a new e-mail account?
If you would like to create an individual e-mail address for your domain (such as [email protected]), please take a look at our tutorials.

Can I install Teamspeak Server or other software on my package web space?
Root access to the server is required in order to install additional software that is not yet available via our panel. For security reasons we cannot provide this for packages - only for dedicated servers or VPS products. If you order your own server of course, you have a free hand to install any software you like.

How much do I have to pay for the traffic?
The traffic is unlimited, so you don't need to care about how much traffic you use every month.

Is it possible to backup my files automatically at your backup server?
Sure, for this reason we offer the '100% Auto-Backup' upgrade.
This upgrade will provide regular backups for your entire webspace package (also databases, configuration settings, etc.) on the exclusive backup server in our data center which is equipped with several hard disks in an expensive RAID 6 array.
With this upgrade, there will be regular backups of your entire webspace package, not only for one state of time, but for three: There will be a daily, a weekly and a monthly backup.
If you want to access one of these backup states, just contact our support team and we will take care of the rest!

With which administration panel can I control my webspace package?
You can administrate your webspace package via the very professional and state-of-the-art web administration tool 'cPanel'.

I need individual software support. Can you please help me?
Our technical experts will be happy to support you with your individual software issues (like the installation of special PHP-scripts, database administration, etc.). This 'remote-hand' service by our IT professionals costs 25 EUR per beginning of each 15 minutes.


Server-specific questions

Can I place an additional order for HDDs/RAM for my server?
Yes, that's no problem at all. After clicking 'Order now!' (no obligation) you are forwarded to the configuration page for the respective product. Here you can view the possible upgrades and can of course, also place an order.
Upgrades can be ordered if you already have a server at Contabo. To do this, please send a short e-mail to [email protected]

Can I do Flash FXP-Server-to-Server-Transfers with my server at Contabo?
You have full root-access on all of our servers, therefore you can disable or enable FXP.

How can I control my VPS / Dedicated Server?
You get full root access (for Linux) or full administrator access (for Windows) to your server. Therefore of course you can install any software you want on your server.
For Linux remote access, please let us recommend the SSH client 'putty' - Windows server can be controlled via the 'Remote Desktop' client.
Additionally, every VPS can be controlled via VNC by default.
Futhermore, there are a lot of options in the Contabo customer control panel for your server. For example, to reboot your server - even if it is not accessible anymore - or perform a complete reinstallation of your server with one of serveral operating systems.

Can I order additional IP addresses for my VPS / Dedicated Server?
It is possible to order up to 20 additional IP addresses per VPS and up to 100 additional IP addresses per dedicated server. The monthly price is 2.00 EUR for each IP address. To order them, please just contact us by e-mail concerning this matter. Our support team is ready to assist you immediately.

How much traffic is included?
The traffic is unlimited, so you don't need to care about how much traffic you use every month.
Furthermore, the bandwidth is shared, which means that a pool of servers shares a bigger bandwidth. We don't oversubscribe our bandwidth capacities unlike many other providers. Thus, generally the full 100 mbit/s or 1 Gbit/s port speed is provided to you anytime.
We only would have to limit the bandwidth if the usage would be permanently much too high. For more details, please just have a look at the specific terms at our offers.
But we also offer dedicated (=unshared) bandwidth with unlimited traffic in predefined packages. These packages can be selected during the order process or at any later point in time via e-mail. With one of these packages you will have the selected bandwidth available at any time, exclusively and unlimited.

I need more bandwidth than included by default, do you offer individual bandwidth upgrades?
We can offer you also dedicated (=unshared) bandwidth with unlimited traffic. Please note that unshared bandwidth is a premium solution: you will have the bandwidth available at any time, exclusively reserved and unlimited. You can define the individual dedicated bandwidth yourself, everything between 101 Mbit/s and 10 Gbit/s is possible! For more details please have a look here. If you want to use individual bandwidth for your services, our support team at [email protected] would be more than happy to advice you in this regard.

Are there any restrictions regarding the content or the software installations on my VPS / Dedicated Server?
In general, our servers are unmanaged root servers. Our customers have exclusive access to their servers. Provided that there are no violations against German law or our ToS (Terms of Service) we do not check what you are using your server for.

Is it possible to order backup space, so that I can backup my data on your backup server?
Sure! We offer various Backup-Space upgrades which can be either ordered directly with your Dedicated Server / VPS or also later via e-mail. Then you can easily backup your data via FTP(S) on one of our high-end RAID 6 backup servers.

I´m connected to my VPS via VNC - but all I see is a black screen
If you see a black screen initially, that is correct, just click into the VNC window and press enter. Your operating system will then respond with the login screen.

I´m trying to log-in to my VPS via VNC and I´m using the correct password, however the login procedure fails
If you have problems logging in with your regular password, that might be due to your keyboard layout, the Y and Z keys may be inverted. In this case, you have to hit the z key when you want to type a y and vice versa.
You can easily test your keyboard settings if you type the password into the user name input field (do not press enter), watch what happens then and compare the password with the result of your entry. If you, for example, enter zzz on you keyboard as username, you see that VNC interprets that as yyy.

Is it possible to host my servers in two different data centers?
Yes, this is possible. Both data centers of Contabo are located in two different cities in Germany, being several hundreds of kilometres far apart from each other and being supplied with electrical power of two different electricity grid operators (SWM and N-ERGIE). All your servers can be targetly placed on both data center locations, without any extra costs. Thanks to this geographical redundancy your services stay online, even if a data center is being destroyed by fire, water or other catastrophes or if the operation is interrupted. Feel free to contact our customer support for any realization inquiries regarding the separation of your dedicated servers or virtual private servers on two different locations.

What is the difference between “HDD + SSD-boost” and “100% SSD”?
When you opt for a VPS from our series “HDD + SSD-boost” you get a virtual server with a standard hard-disk (HDD) and an additional SSD-boost. Consequently, you receive a lot of disk-space for your data and at the same time the SSD-boost ensures that your VPS has a strong I/O performance. Compared to ordinary VPS without SSD-boost, our servers offer you a much quicker access to your data.
In our new series “100% SSD” we only use the latest solid state drives (SSDs), which are much faster than standard hard-disks (HDDs). As a result, the performance of your VPS increases significantly since all your data is stored on SSDs only and can be handled with a much better read-write speed.

How do snapshots from the VPS series “100% SSD” work?
Our new VPS-SSD series offers you the possibility to create so-called “snapshots” of your system. This means that the current state of your system is saved and stored. This is a useful tool which allows you to run risk-free updates of apps or install new software on your system. In case you encounter any issues afterwards, you can easily “rollback” your system to its previous state. You can perform a snapshot yourself through your Contabo customer control panel by clicking the “Create snapshot” button. If you want to reset your system at a later point in time, simply click the “Rollback”-icon. You can find more information in our tutorial Snapshot feature for the new VPS SSD.

Is a snapshot the same as a system backup?
No, when you create a backup you can then restore single files or folders. A snapshot allows you to restore the entire system only. It is especially useful to generate a snapshot in case you like to try out new applications. Whenever you encounter issues, you can simply reset your system to its previous state with just one mouse-click.

Can I create snapshots at will and save them forever?
Depending on your VPS-SSD model, you may save between one and four snapshots at the same time. Please note that a snapshot will be deleted automatically after 30 days. You can see the date of its creation as well as the date of its auto-deletion in your Customer Control Panel when you click the snapshot-icon.
Regarding the rollback, please keep in mind: If you have, for example, saved three snapshots and you select to restore the system status from the middle snapshot (chronologically speaking), the most recent snapshot will be deleted automatically. You cannot return to that snapshot afterwards. Only the oldest one is then still available.

Is the new snapshot function available for all VPS?
No, this new function is only available for our VPS of the series “100% SSD”. If you purchase (or own) a VPS of the series “HDD + SSD-Boost” you can create your own backups. For that we do offer you the option to rent additional disk-space on our specific backup servers.

I am a VPS customer of yours already. Can I move with all of my data to one of your fast VPS-SSD?
No, due to their different architecture the two VPS-series are incompatible. You can only upgrade with a confirmed “loss of data”, which means that all your applications will have to be installed again by yourself on your new SSD VPS.
The same applies in case you want to move from a SSD VPS to one of our VPS with HDD and SSD-boost.

The VPS-SSD are more expensive and have less storage space. Does it make sense for me to rent one of those or even to move to a SSD VPS from my existing VPS?
Compared to standard hard-disks (HDDs), SSD disks are currently much more expensive. We have tightly calculated the best possible price for you.
It is up to you to consider your needs: If you either require a lot of disk space (maybe then one of our dedicated servers is an option for you as well) or if you focus on quick access time because you operate databases and applications that process many read and write tasks per second.

Generally speaking: SSD disks are superior to standard hard-disks with regard to their speed and longevity. After all these flash-disks do not contain any mechanical or movable components which could break down. By the way: Their price decreases over time – and we always forward lower prices to our valued customers.


Colocation- and bandwidth-specific questions

Where is the data center of Contabo located and how is it equipped?
Contabo operates two own data centers providing all kinds of hosting and colocation services. Our ultra-modern "Green Data Center" in Munich was planned and built in 2009 specially by Contabo. It is able to accommodate 4.000 server systems. Our second data center, located in Nuremberg, was taken into operation in 2014 and has space for further 10.000 server systems. At both sites, our office and support rooms are situated in the same building, just one floor above the data center.

In terms of your operational reliability and energy efficiency both data centers are on the cutting edge of modern technology. Every year Contabo invests a large amount in maintenance and optimization of the entire data center infrastructure in order to provide a stable and, thanks to low operating costs, a cost-effective platform for the server operation.

Our colocation customers are able to choose directly in the menu of our website (during the order process) whether they like to place their server in Munich or Nuremberg (or both in case you want to colocate more than one server at two different places).

Further details regarding both of our data centers can be found here. Live-webcams are online 24/7 - you can find them here.

Can I colocate any type of server - including self-assembled servers - at Contabo?
Generally: Yes. You should, however, take care that rack servers meet the standard dimensions of 19"-racks and that tower servers (servers with normal PC-cases) do not exceed the following dimensions:

height: 41 cm
width: 19.5 cm
depth: 48 cm

Should a rack server take up more than one U in the rack, or should a tower server exceed the dimensions outlined above, additional housing modules become necessary. The same is true when the average power consumption exceeds the maximum power available with an offer.

If you, for example, want to colocate a tower server with the following dimensions: 50cm x 22cm x 45 cm (hxwxd) and an average power consumption of 170 watts, two standard housing modules will be necessary.

Finally, it is your task to ensure that all hardware and equipment, which is sent in, is secure and cannot cause damage to the facility or other equipment.

How can I send my server to you and how is it taken online?
Once you have ordered the desired housing module, power module and bandwidth module,, you can send your server to our data center (we can recommend UPS as logistics company because their handling of packages is reasonable). Please include a note containing your full name as well as your customer-ID and additional information which enables us to identify you. If there are special instructions regarding the setup of the server, please also include them with the package.

Once your server and the first payment have arrived we will let you know about our address and setup your server and connect it to the Internet.

Of course, we will provide you with the IP information for your server before you will render the server to us.

What is the speed with which my server will be connected to the Internet and how does billing for traffic work?
You alone can decide about the speed (bandwidth) with which you server will be connected to the Internet:
After having chosen the desired housing module, you can choose the bandwidth module. This module determines the connection to the Internet of your server and how billing is handled. You can, for example, choose the standard connection, a so called 'shared bandwidth pool' with no traffic limit at 9.99 EUR / month. You can also choose 'dedicated' bandwidth, which is reserved entirely for your server and is usable in full only by you, all the time. The price of dedicated bandwidth depends on the number of mbit/s you want to order.
Details on all bandwidth offers can be found on our offers page.

I want to buy the Hardware from Contabo to then use it for the Colocation offers. Is that possible?
Sure, please just contact our support team with your hardware requirements - we will be more than happy to send you our offer.

I have very individual requirements for my colocation equipment, can you therefore also offer individual solutions?
As we run our own high-end data centers in Munich as well as in Nuremberg, Germany, we are very flexible regarding any special requirments. No matter if you want for example to use special telecom equipment, your own racks or full cage solutions - we will be more than happy to send you our individual offer.

Is it possible to colocate my servers in two different data centers?
Yes, this is possible. Both data centers of Contabo are located in two different cities in Germany, being several hundreds of kilometres far apart from each other and being supplied with electrical power of two different electricity grid operators (SWM and N-ERGIE). All your servers can be targetly colocated on both data center locations, without any extra costs. Thanks to this geographical redundancy your services stay online, even if a data center is being destroyed by fire, water or other catastrophes or if the operation is interrupted. Feel free to contact our customer support for any realization inquiries regarding the separation of your servers on two different locations.

Is it possible to receive a satellite feed?
Yes, you can receive signals of Astra 19.2°E or Eutelsat Hot Bird 13.0°E in our Nuremberg data center. The satellite feed is available both for colocated servers as well as for dedicated servers. No additional hardware is required from your side, neither in the server itself nor peripheral to it, because you will receive the satellite feed on your server directly via Ethernet. Since a separate network card is used for this service, your regular uplink will still be able to run at full capacity. HD is supported. This is all made possible by the upgrade "satellite feed" which you can select during the order process. You can switch between channels of Astra and Hot Bird at any time. It is even possible to receive channels of both satellites simultaneously if you order the upgrade twice (you will receive two network cards in this case).


IPv6 specific questions

IPv6- What is it all about?
IPv6 is a new protocol which exists already and which presently operates simultaneously with IPv4. It will supersede IPv4 in the future.

IPv4 addresses are the ones known today, which consist of 4 numeric blocks divided by a dot. Due to the ever faster growing Internet structure and the continuously expanding number of devices connected to it, IPv4 addresses have become scarce by now. Technically, however, it is not possible to expand the number of IPv4 addresses, and therefore, a completely new protocol has been created with IPv6. This incorporates a substantially bigger number of addresses and is capable of coping with future challenges and requirements.

How do I recognize a IPv6 address?
Since IPv6 addresses are entirely different from IPv4, they can be identified easily. IPv6 addresses in their normal configuration consist of 8 hexadecimal tuples, divided by a colon. Here is an example of such an IP address:

2607:f8b0:400c:0c03:0000:0000:0000:0069

How can I use IPv6 on my virtual or dedicated server at Contabo?
For establishing a connection with your server at Contabo with IPv6, it is necessary that your ISP already provides IPv6 and that you are using IPv6 when browsing the Internet. For testing purposes as to whether or not you are using the IPv6 protocol already, please try the following link: http://test-ipv6.com

With each VPs or dedicated server, you will get an assignment of 65.535 additional IPv6 addresses that you can use upon your own discretion without limitations. Of course, you will still get one IPv4 address with your VPS or dedicated server, which ensures that you can use all our products, even if you are not yet participating in IPv6.

How do I configure IPv6 on my server?
When placing a new order at Contabo, your dedicated server or VPS will already be prepared and preconfigured with IPv6, so that you can reach your server via IPv6 immediately upon receipt of the login details. The manual setup of IPv6 on your server differs only marginally from setting up an IPv4 address. You can find detailed intructions for all common operating systems in our tutorial: https://contabo.com/?show=tutorials&tutorial=adding-ipv6-connectivity-to-your-server
