\* there are some anomalies in OONI for RU, but they are not higher than some coutries like CA
\* most of snowflake users are comming from Russia, it works at least for some
\* stunreachability measurements show 3 \(of 12\) STUN servers inaccessible in Russia, 2 blocked by Russian ISPs, 1 possibly geoblocking of users in Russia
