Hi,

You are running a fast Tor relay, which is great:
http://rougmnvswfsmd4dq.onion/rs.html#details/32E6CC6C6B428B2043F0B3E78F7332F1016D73E1

But that Tor version is obsolete, and because of old bugs, we will soon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!

The Tor 0.3.5 long-term-stable branch will be maintained until Feb 2022:
https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorReleases#Current
and you can see the lifetimes of other Tor versions on that table too.

You can find Tor packages for your distro / OS here:
https://trac.torproject.org/projects/tor/wiki/TorRelayGuide#PlatformspecificInstructions

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!
