Comment (by mcs):

 Replying to [comment:13 isis]:
 > Off the top of my head, I have no idea what this is about, other than
 perhaps the networking code in FF perhaps trying to do something "smart"
 which interacts badly with meek-server?

 That's a good theory, although meek works as a PT within Tor Browser.
 Hmmm.

 `017d0f33d7270ff102fe167f1c16def8b3e3be4a` from the end of March. That
 makes sense because that's around the time I did #16650. (I'm not sure if
 anything in the client/server implementations have changed enough to make
 this incompatible?)

 I don't know either. David?

 > So the bridges are assigned to a distributor when they are first seen,
 and they can't be reassigned, in order to keep potential discoverability
 problems with any particular distribution method locally isolated.
 BridgeDB logs these assignments, and, grepping the latest assignments.log,
 it seems like it has 100 bridges for the moat distributor so far. (It's a
 known issue that adding a distributor would take a while to fill up with
 bridges since the way it works is that is has ratios and it assigns
 according to those ratios instead of bringing the levels to the correct
 ratios… I could fix that if we want.) But in any case, with 100 bridges,
 you should be getting at least 1 bridge back? Are you connecting to the
 meek-reflector over tor?

 No, we are not connecting over tor. Is that a requirement?
 I have never receive a bridge, not even one :)
