General

With Data Center we are referring to both the building, the premises where the servers of one or several companies or organizations are housed, as well as the organization itself who takes care of these servers. The common abbreviation is DC.

To which backbones are the Data Centers connected?

See: https://www.hetzner.de/en/hosting/unternehmen/rechenzentrum

How are the Data Centers connected to each other?

The two Data Center Parks are both connected to Frankfurt (FFM) and each other with dark fiber. Thus, a redundant loop is formed, which ensures the availability of a Data Center should one of the connections fail. The n*10 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. Through the Frankfurt location data is transported to the peering partners at DE-CIX and also to the 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 several Juniper EX Core switches, each with 64x 10 Gbit/s ports, are operated and bundle the streams of the Data Center to the n*10 Gbit/s backbone and then over the various uplinks.

In which Data Center is my server located?

Make a trace to the IP address of your server. 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:

1    4.764 ms   4.748 ms   4.739 ms  M-EA1.M.DE.net.DTAG.DE (194.25.0.209)
2    6.893 ms   6.894 ms   6.885 ms  217.239.48.234 (217.239.48.234)
3    6.114 ms   6.307 ms   6.102 ms  ae0-3321.fra10.core-backbone.com (87.128.234.66)
4    6.272 ms   6.069 ms   6.063 ms  ae2-2020.fra20.core-backbone.com (80.255.15.34)
5    6.053 ms   6.043 ms   6.037 ms  core-backbone-100g-fra.hetzner.de (80.255.15.122)
6    6.019 ms   6.316 ms   6.298 ms  core4.hetzner.de (213.239.245.2)
7   10.643 ms  10.824 ms  10.751 ms  core21.hetzner.de (213.239.245.13)
8   11.075 ms  10.717 ms  11.055 ms  juniper2.rz10.hetzner.de (213.239.245.46)
9   13.873 ms  13.868 ms  13.858 ms  hos-tr2.ex3k9.rz10.hetzner.de (213.239.227.170)
10  11.423 ms  11.417 ms  11.410 ms  <your_server> [78.46.xxx.yyy]

In this example you can see that the server is located in Data Center 10 (rz10). If the penultimate 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 a direct peering.
