== Discussion ==
* Do we have graphs about telegram bridge usage
* irl has some script to generate them
* current telegram bridges are not pressent in metrics.tpo as 'distributor telegram', as they are manually feeded. This will change when we start using rdsys for it.
* Is the reading group reading supposed to be "Web censorship measurements of HTTP/3 over QUIC" https://dl.acm.org/doi/abs/10.1145/3487552.3487836 ?
* or the threads Blocking of HTTP/3 (QUIC) in Russia · Issue #108 · net4people/bbs · GitHub Ограничение HTTP/3 (QUIC) - Russia - NTC ?
* one of the authors of the paper, Kathrin Elmenhorst, has posted some more recent measurements of HTTP/3 blocking in Russia specifically Broad blocking of HTTP/3 traffic in Russia (AS31213, AS12389) · Issue #4 · kelmenhorst/quic-censorship · GitHub
* we'll read the paper, the threads are for more context
* Snowflake Multi-Server Broker Testing (Distributed Snowflake Server Support (#40129) · Issues · The Tor Project / Anti-censorship / Pluggable Transports / Snowflake · GitLab)
* (this is where the client tells the broker&proxy what bridge it wants to use, by putting fingerprint=1234ABCD... on its Bridge line)
* testing is wellcome...
* there are instructions for testing it in the issue
* Report of CDN Block in Turkmenistan(Blocking of Snowflake in Turkmenistan, 2021-10-24 (#40024) · Issues · The Tor Project / Anti-censorship / censorship-analysis · GitLab)
* cloudflare is being blocked in Turkmenistan
* in Russia they are blocking 2 IPs of cloudflare too, but might be an error of overblocking targeting a single site Не открываются некоторые сайты за Cloudflare CDN - #24 by User69 - Russia - NTC
* shell will talk with fastly and cloudflare to see what they know, and we'll look into setting up a vantage point in TM
* meskio, if you could give rdsys a free software license, i will breathe easier at night: rdsys needs a free software license (#107) · Issues · The Tor Project / Anti-censorship / rdsys · GitLab
* meskio will add 3-BSD in the comming days
* dnstt, next steps
* Add support for dnstt (#40001) · Issues · The Tor Project / Anti-censorship / Pluggable Transports / pluggable transports · GitLab
* the major blocker now is to have support for PT commands over the SOCKS connection
* will require forking the code into tpo
== Actions ==
*
== Interesting links ==
* Pluggable Transports April 2022 Meetup - Pluggable Transports
== Reading group ==
* We will discuss "Blocking of HTTP/3 (QUIC) in Russia" on Apr/28th/2022

* Blocking of HTTP/3 (QUIC) in Russia · Issue #108 · net4people/bbs · GitHub
