Comment (by dcf):

 Replying to [ticket:32657 cohosh]:
 > This almost certainly due to blocking, and as ambleclarity recently
 confirmed in #32597, not due to the blocking of STUN servers.

 Could it also be exacerbated by #32129, which has the proxy-go's polling
 every 5 s and the web-based proxies polling every 300 s? Blocking the
 single proxy-go IP address would therefore block a large fraction of
 effective proxies.

 But even so, that should only cause a failure rate of about 10%. https
 ://snowflake-broker.torproject.net/debug says:
 {{{
 current snowflakes available: 41
         standalone proxies: 4
         browser proxies: 0
         webext proxies: 37
         unknown proxies: 0
 }}}
