We can rely on Onionoo to tell us when relay addresses change, so we don't need to record or check them.

This simplifies maintaining the fallback whitelist, and also simplifies the script.

We should probably still put the full details in the blacklist, but that's rare. We can use for that.

We'll still need to check and warn if fallbacks don't have a DirPort. At least until stem gets ORPort support (#18856), and we modify Tor and the script to accept relays without DirPorts (#19129).

Per our triage process, these tickets are pending removal from 0.3.4.

These tickets, tagged with 034-removed-*, are no longer in-scope for 0.3.4. We can reconsider any of them, if time permits.

We should do this ticket in 0.3.4 or 0.3.5, because it's fast, and it lets us skip this slow step in the fallback rebuild process:

  • running the script, finding change warnings, contacting operators, and updating their details

8/150 = 5% of fallbacks are currently down.
At this rate, it will be 2019 before we reach our 25% failure threshold.
So we don't need to do a fallback rebuild in 0.3.4.

Note: See TracTickets for help on using tickets.
