== Discussion ==
* Snowflake doesn't work in Russia (connection failure by timeout)
* IRC Tip about Signature used to block Snowflake in Russia, 2022-May-16 (#40030) · Issues · The Tor Project / Anti-censorship / censorship-analysis · GitLab
* Snowflake blocked by ClientHello [RU] (#40140) · Issues · The Tor Project / Anti-censorship / Pluggable Transports / Snowflake · GitLab
* A new Snowflake blocking rule (offset of supported_groups in DTLS Client Hello) - Russia - NTC
* the new reported blocking rule, with a different offset to supported_groups than what we diagnosed in December 2021 (Make Snowflake's DTLS fingerprint more similar to popular WebRTC implementations (#40014) · Issues · The Tor Project / Anti-censorship / Pluggable Transports / Snowflake · GitLab) is real
* however Snowflake still works in Russia, apparently
* Is there a tool to do automated bisection of packet contents and discover such blocking rules?
* OONI once had a module called daphn3
* ooniprobe-debian/daphn3.py at master · OpenObservatory/ooniprobe-debian · GitHub
* OONI and Daphn3 - Speaker Deck
* Also Geneva could work for this purpose https://geneva.cs.umd.edu/
* polyanthum got upgraded to bullseye
* everything is working except for bridgestrap metrics
* Any anti-censorship stands/activities at MCH2022 (https://mch2022.org/)?
