 team/2016-September/000216.html Karsten writes] that 2016-09-02 was the
 date that [https://blog.torproject.org/blog/new-bridge-authority the new
 bridge authority Bifroest took over from Tonga], causing
 about 40%] of public bridges to stop reporting. If that 40% was
 disproportionately obfs3, that might help explain what we're seeing.

 I don't see how the changed bridge authority could have an effect on the
 number of ''direct'' users, so the fact that direct and obfs3 users both
 decreased on 2016-09-02 could be a coincidence. I just took "obfs3" out of
 the ticket title.
