Hi Simon,
You are running a Tor relay, which is great: http://rougmnvswfsmd4dq.onion/rs.html#details/7F1BE66D43623CF81058837ED8D333...
First: that Tor version is obsolete, and because of old bugs, we will soon cut relays running those versions out of the network.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 your distro / OS here: https://trac.torproject.org/projects/tor/wiki/TorRelayGuide#Platformspecific...
Ideally you will switch to keeping up with our stable releases, but if you need a stable that is especially stable, the Tor 0.3.5 branch will be maintained until Feb 2022: https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorR... and you can see the lifetimes of other Tor versions on that table too.
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
