   16:19:56 <anadahz> Confused about the meek client metrics in Turkmenistan -- https://metrics.torproject.org/userstats-bridge-combined.png?start=2021-08-02&end=2021-11-04&country=tm
   16:20:39 <anadahz> How come and there are so many meek clients in Turkmenistan?
   16:20:54 <dcf1> Here is a graph with some more context

   16:21:00 <meskio> does it look like related to snowflake going down?
   16:21:13 <dcf1> however zoom out a bit to get even *more* context (esp. wrt relay users)

   16:21:23 <cohosh> related info on tor blocking in TM: https://gitlab.torproject.org/tpo/community/support/-/issues/40030
   16:22:10 <dcf1> to me it looks like OR and meek were rising simultaneously, then snowflake and OR got blocked.
   16:22:33 <cohosh> wow
   16:22:49 <meskio> blocked? or our failure with probetest?
   16:23:45 <dcf1> but snowflake users globally did not go to zero in the same way https://metrics.torproject.org/userstats-bridge-transport.html?start=2021-08-06&end=2021-11-04&transport=snowflake
   16:24:05 <anadahz> On 2021-10-31 the amount of meek clients count were almost spike to 1,5 times than before.
   16:24:05 <meskio> I see what you mean :(
   16:24:09 <cohosh> yeah this looks suspiciously close to zero
