Comment:

 Here are all the related tickets:

 When Tor can't download microdescriptors (#21969), maybe it should try
 authorities or fallbacks (#23863), before it runs out of microdesc retries
 (#24113). But even after Tor has the microdescs it needs, it sometimes
 doesn't start building circuits again. Instead, it is in state "waiting
 for circuit" (#25347).
