In July, we went from 1% of fallback directory mirrors being down, to about 10% of fallback directory mirrors being down. See "Fallback Directories Running, Past 90 Days" on: https://consensus-health.torproject.org/graphs.html (Needs JS, SVG) This means that 10% of client requests go straight to directory authorities. For the other 90%, the first fallback and first directory authority request happen simultaneously, and the authority often wins (and gets to supply the client's first consensus). Deploying #17750 in 0.3.2 (or backporting it to earlier releases) will fix both these issues: > If we want to reduce the load on authorities, we can backport this > change, which makes clients try fallbacks before authorities: > > https://trac.torproject.org/projects/tor/ticket/17750 > > It's been in master (0.3.2) for almost 2 months now.
