Comment (by arma):

 Now that 0.2.9.5-alpha is out (which we think fixes #20499, right?), it
 might make sense to look through #20501 and see which relays are buggy,
 and contact their operators to get them to upgrade?

 That said, the question I think is not whether it is delivering a bad
 consensus right now. The question is whether it is running the buggy
 versions.

 Maybe a stem script to take in the list of fallback dirs, and output the
 ones that are running a buggy version, would be what you want? Then we can
 re-run the script periodically until we reach the point where we want to
 un-fallbackdir the ones that stubbornly remain. (And somewhere in there we
 should do the "send mail to all the operators running buggy versions to
 let them know that they need to upgrade. Pretty soon I think, right? Once
 0.2.9.5-alpha packages are out and ready?)
