Use the same fallback directory mirror to bootstrap

If Tor always tries to use the same fallback directory mirror to bootstrap (when the consensus expires because Tor isn't used), fewer servers learn about Tor clients, and a Tor client is less likely to download from a bad fallback directory mirror.

This is low priority, as most Tor clients only bootstrap once [citation needed].

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
