Comment (by dcf):

 It looks to me more like it's the ''end'' of some weirdness that begain in
 2017. The states from the UAE have been weird for a long time and we don't
 know why. My guess is that this is not a blocking event or a loss of real
 users, but rather something else artificial. Here is the decrease with
 more context:

 These are the relevant [[doc/MetricsTimeline]] entries (I'm about to go
 refactor these):

 For a while, there was also a weird increase in obfs3 users in the UAE.
