[anti-censorship-team] Snowflake (DTLS) block in Russia

[ValdikSS]

Hello eveyone,

There's ongoing Tor block on certain Russian ISPs, which on top of 
everything else includes Snowflake censorship using DPI.

DTLS connection never establishes and gets filtered in 
ClientHello/ServerHello sequence.

Check the attached dumps from Tele2 cellular operator (as12958) made on 
3 and 6 December 2021.
