Here I try to map the current internet blocks AFAIK, so others can look into them after the break (I'll be AFK next week). # Russia ## situation Main issue: https://gitlab.torproject.org/tpo/anti-censorship/censorship-analysis/-/iss… FTE (obfs4) is blocked in mobile networks: https://gitlab.torproject.org/tpo/anti-censorship/censorship-analysis/-/iss… webtunnel is being actively listed: https://gitlab.torproject.org/tpo/anti-censorship/censorship-analysis/-/iss… ## ideas Does it make sense to start using conjure in Russia? It might solve the problem until we have dynamic webtunnel bridges. Maybe we can start with the community team distributing a bridge line to some users, and not jump all in with the circumvention settings. As we haven't seen many users in conjure yet. Should we explore integrating the domain fronting idea the community has developed in webtunnel and see if we can do something more on this. # Iran ## situation Partial block of snowflake: https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… ## ideas Requesting more proxies: https://gitlab.torproject.org/tpo/community/relays/-/issues/116 The community team will need help on this, producing screenshots of grafana or other data for the campaign. We have our vantage points back in the country. I haven't had the time to investigate much. I guess we'll need to figure out if Iran is blocking proxies by fingerprint or by listing them. # China ## situation meek is blocked: https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/162 ## ideas Do this affects also to snowflake and/or moat? Looks like phpmyadmin.net is reachable, but maybe they fingerprinted our meek implementation? if so moat will not work either. Or some other problem with CDN77. We do have a vantage point in China, isn't it? I don't have access to it, maybe something to add to vaultwarden. Maybe someone can investigate this and see how far the block goes? Do we need to move to speed up the migration of moat to netlify? -- meskio | https://meskio.net/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- My contact info: https://meskio.net/crypto.txt -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Nos vamos a Croatan.
