Comment (by dcf):

 Replying to [comment:32 mwolfe]:
 > Today, I got Tor 8.a3 and it worked without any bridges. I wasn't sure
 if the UAE stopped blocking Tor, or if 8.a3 fixed the problem, so I tried
 one of my old Tor 7.a and it could not load the network without meek,
 while 8.a3 can load without any bridges.

 Hmm, maybe it has to do with the new directory authority bastet, which got
 added in Tor Browser 7.0.10 (2017-11-14) and 7.5a8 (2017-11-15), and had
 an IPv6 address added in Tor Browser 7.0.11 and 7.5a9 (2017-12-09). The
 existing directory authority Longclaw also changed its IP address in Tor
 Browser 7.0.10/7.5a8.

 If the censors are only blocking directory authorities, such a change may
 have caught them off guard. If it's not that, I'm not sure what it could
 be.

 I just added entries related to the above to the metrics timeline:
   [[doc/MetricsTimeline?action=diff&version=239&old_version=237]]
