Replying to [comment:2 teor]:
> This issue occurs because a directory guard that is missing
microdescriptors we need is still considered live. We only mark a guard
dead when we fail to connect to it. (When all guards are marked dead, we
use a fallback or authority to fetch microdescriptors).
IIUC a directory guard can be naturally missing microdescriptors because
they still have not propagated to the network sufficiently, so marking it
as a dead guard at that point is probably an overkill (aka we might end up
marking many (directory) guards as dead for no reason). Perhaps you mean
marking it as dead for the purpose of fetching that '''specific'''
microdescriptor and just skip to the next directory guard for fetching
that md? I think some sort of logic like that would be useful, especially
when considering important mds like the primary guard mds (#21969).
