Comment (by teor):

 Replying to [comment:4 Sebastian]:
 > Load on dirauths is extremely light right now IMO. Having clients
 contact dirauths would be bad, but having relays contact dirauths early
 and a bit more aggressively (and maybe having dirauths ultra-aggressively
 try every other dirauth) doesn't sound like the end of the world to me. I
 am currently seeing less than 3MB/s (averaged over 30 second intervals)
 peak outgoing bandwidth on my dirauth which is basically negligible.

 I am not sure we can have relays try fast enough to make sure this bug
 never happens on clients. That would cause issues every hour from about
 hh:00 to hh:01.

 Why don't we have clients remember where they got the consensus, and try
 it for any missing microdescs before trying an authority?
