Hi Matthias,
You are running a Tor relay, which is great: http://rougmnvswfsmd4dq.onion/rs.html#search/7574975BA76DE0726231FC916DD70B0...
First: that Tor version is obsolete, and because of old bugs, we will soon cut relays running those versions out of the network. Please consider upgrading!
Second: let us know if there is any way to help you bump up the bandwidth that you are allocating to the Tor relay. :)
You can find Tor packages for many distros / operating systems here: https://trac.torproject.org/projects/tor/wiki/TorRelayGuide#Platformspecific... and/or here: https://community.torproject.org/relay/setup/
Let us know if we can do anything to make the process easier.
And lastly, I am cc'ing the new network health mailing list (which has public archives), to help us stay synced: https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkHealthTeam
Thanks! --Roger
