If you're interested in avoiding slow fallback directories any reason not
to simply run the script I gave above when picking them?
So I'm doing that when I pick them, but what if they become slow some time
after the release?
Also, in #18812, we realised that we'd like to check that the fallback's
current key matches the one in the source code.
So can you modify DocTor to call a fallback "failed" if:
* it doesn't respond to an ORPort request, or
* (almost all clients will connect to the ORPort and issue a begindir
request)
* the key doesn't match the one in the fallback list, or
* it takes longer than 15 seconds to serve a consensus
(Are these doable? Is the amount of effort ok?
The current checks are still quite useful.)
It's ok to have a few fallbacks fail.
But I'd like to know when 25% of fallbacks are failing, so that we can
update the list in the next point release.
How do I get that email/notification?
