#21506 closed defect (fixed)

Client with current microdesc consensus but no descriptors chooses down fallback every time

Tor doesn't have the fix for a similar issue in #20996, but does.

But this issue is different from that issue: the client downloads the consensus, then tries the same fallback (a down fallback) every time.

This really shouldn't happen: the client should choose a different relay every time.

My guess is that this relay is chosen because it's down, and all the up relay descriptors are unavailable. This is pathological behaviour.

I think we fixed it in with the patch to #20996, but I'm logging this bug just in case.
