Georg Koppen:
Hello!
Relays running unsupported Tor versions is a problem we have never really dealt with in a systematic way in the way. Some of you might recall that we (with the help of volunteers) tried back in 2019/2020 to get operators, running an unsupported Tor version, to upgrade[1] but then we dropped the ball. Alas.
We just started that process again by contacting every relay operator running an outdated Tor version (any version not 0.3.5.x or 0.4.5.x or 0.4.6.x or 0.4.7.x) by email where possible. Additionally, we created a wiki page outlining the current process and things we still need to figure out.[2] On that page we plan to make statistics related to the EOL relay removal available as well, including the final list of relays we'll reject. Thus, stay tuned. Feedback, as always, is very much welcome!
Alright, I collected all the fingerprints of relays still running an EOL version (that is, relays running none of 0.3.5.x, 0.4.5.x, 0.4.6.x or 0.4.7.x), which are 449, and prepared a commit to reject those. This rejection will likely happen at some point in the next couple of hours once a majority of directory authorities has picked up that commit.
At the same time I updated the wiki[2] adding all the relay fingerprints of those relays, so we have a public record.
If this is affecting anyone of you, please upgrade your relay to a supported Tor version and get in touch with us (off-list), so we can help you getting the relay unblocked again.
Thanks, Georg
