Thank you Philipp, I have upgraded my Tor bridge to 0.4.2.6.

I'm running it on my Raspberry Pi, and the issue was that the tor version included in Raspbian's standard repo is still 0.2.9.16 -- this could be the cause for a lot of outdated nodes.

Hi there,

You seem to be running the following Tor bridge, which is great:

64DF5E59804B058E64BF19B6992F1330C73B2CF4

But that Tor version (0.2.9.16) is obsolete, and because of old bugs, we will soon cut bridges running those versions out of the network. Please consider upgrading!

You can find Tor packages and instructions for your distro / OS here: https://community.torproject.org/relay/setup/bridge/

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 copying 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, Philipp
