General
With "data center" we mean the building itself, the space inside the building where we house the servers of one or several companies or organizations, and the organization itself who takes care of the servers. The common abbreviation is DC.

Which backbones are the data centers connected to?
See: https://www.hetzner.com/unternehmen/rechenzentrum/
How are the data centers connected to each other?
All Hetzner data center parks are connected to our backbone via redundant dark fiber connections. This ensures the availability of a data center if one of the connections fails. The n*100 Gbit/s connections provide ample bandwidth between the data centers.
The bandwidth of the connections between Nuremberg-Frankfurt, Nuremberg-Falkenstein and Falkenstein-Frankfurt are at least 120 Gbit/s. Our Frankfurt location transports data to our peering partners at DE-CIX and also to the following uplinks: Noris, GLBX, Aixit, AMS-IX, Init7 and Level3. At the Nuremberg location, there are connections to Noris, KPN, Init7, Level3 and N-IX.
In each data center, we operate several Juniper EX Core switches and bundle the streams of the data center to the backbone and then over the various uplinks.
In which data center is my server located?
Make a trace to your server's IP address. On Windows, the command is:
tracert <your\_IP>
On Linux, the command is slightly different:
traceroute <your\_IP>
The initials in the name of the hops in front of your server shows you the data center:
2 217.0.117.200 (217.0.117.200) 18.149 ms 17.080 ms 16.750 ms
3 87.190.176.130 (87.190.176.130) 17.602 ms 17.786 ms 17.778 ms

11 eigenerServer (vvv.xxx.yyy.zzz) 26.959 ms 26.807 ms 26.958 msIn this example, you can see that the server is located in FSN1-DC3. If the second-to-last hop shows a name in the form of xxx-yyy-zzz-xxx.clients.your-server.de, then a correct rDNS name has not (yet) been assigned to the corresponding router.
Peering Policy
Our primary goal is to exchange traffic, as far as possible, at central exchange nodes, such as DE-CIX, AMS-IX, DATA-IX and V-IX. In addition, we follow an open peering policy, so that everyone who wants to can organize a peering with us there. We are also open for the private interconnection of routers, should it make sense from a technical or economic point of view.
For all targets that cannot be reached via a private peering or via a peering point, we route traffic through 2 of the leading transit providers. If another route is desired, we are always open to setting up a direct peering.
