Comment (by cohosh):

 Thanks for the updates amiableclarity2011 and cypherpunks.

 As stated before, the current issues are almost certainly not caused by
 the GFW.

 There are two problems: 1) it takes a very long time (30s) to discover
 that a snowflake isn't working, and 2) there's no way to recover sent data
 once the client has a new snowflake. These are both being tacked in
 #29206. The review/revision turn around on that has been very slow,
 partially due to the fact that this requires large changes to both the
 client and the server.

 In the meantime, we've been deploying smaller fixes that should help as
 people update their proxies: #31391 was recently deployed which should
 eliminate proxies that can't connect to the bridge and #32129 will hand
 out proxy-go instances more frequently than web-based proxies (which is
 likely where the problems are still coming from).

 Thanks for the continued updates and your patience. This is still in alpha
 and we are dealing with our first ever wide-spread deployment of web-based
 proxies. We're still figuring out the engineering challenges of dealing
 with proxies that are unreliable or slow to update.
