Comment (by teor):

 I am very happy with the current set of fallbacks, which we generated in
 January 2018 using a minimum 90 day stability period.
 (The previous stability period was 30 days, which was too low - it led to
 a rebuild after ~6 months,)

 We have only lost 8 falllbacks after ~3 months:
 https://consensus-health.torproject.org/graphs.html

 At this rate, it will take us ~14 months to lose 25% of our 150 original
 fallbacks (or ~38 fallbacks).
 But we also want to rebuild the list every 12 months, so let's rebuild in
 January 2019 at the latest, or 0.3.6:
 https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorReleases#Current

 If we're still doing well with fallbacks in 3-6 months' time, let's send
 out an email to thank all the fallback operators.
