commit 396bddaa4c48453fcc6583188622cc0edf766fa1 Author: teor teor2345@gmail.com Date: Wed Dec 7 16:03:32 2016 +1100

Require fallback directories to have the same address and port for 7 days

7 days is a tradeoff between the expected time between major Tor releases, which is 6 months, and the number of relays with enough stability.

Relays whose OnionOO stability timer is reset on restart by bug #18050 should upgrade to Tor 0.2.8.7 or later, which has a fix for this issue.

Closes ticket #20880; maintains short-term fix in e220214 in tor-0.2.8.2-alpha. --- changes/fallbacks-201612 | 9 +++++---- scripts/maint/updateFallbackDirs.py | 11 +++++++---- 2 files changed, 12 insertions(+), 8 deletions(-)
