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:

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
4   217.239.47.14 (217.239.47.14)			21.653 ms  21.880 ms  22.086 ms
5   ae8-0.fra20.core-backbone.com (62.157.251.158)	31.661 ms  22.087 ms  22.106 ms
6   ae1-2014.nbg40.core-backbone.com (81.95.15.206)	26.164 ms  23.759 ms  24.207 ms
7   core-backbone-100g-nbg.hetzner.de (81.95.15.6)	25.032 ms  25.771 ms  25.485 ms
8   core11.nbg1.hetzner.com (213.239.229.161)		26.463 ms  26.234 ms  26.000 ms
9   core22.fsn1.hetzner.com (213.239.245.213)		27.311 ms  25.535 ms  25.825 ms
10  ex9k2.dc3.fsn1.hetzner.com (213.239.229.246)	26.027 ms  26.072 ms  26.317 ms
11  eigenerServer (vvv.xxx.yyy.zzz)			26.959 ms  26.807 ms  26.958 ms

In this example you can see that the server is located in FSN1-DC3. 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.
