Anti-censorship work meeting pad



Next meeting: Thursday November 11th 16:00 UTC

Weekly meetings, every Thursday at 16:00 UTC, in #tor-meeting at OFTC (channel is logged while meetings are in progress)

== Goal of this meeting ==

Weekly checkin about the status of anti-censorship work at Tor.
Coordinate collaboration between people/teams on anti-censorship at Tor.

== Announcements ==

     we will be posting monthly reports on the new discourse forum


== Discussion ==

     Staging and deployments of rdsys/BridgeDB

     there are a lot of big changes coming to our deployment of BridgeDB, we want to make sure it's thoroughly tested in a production environment

     polyanthum (the machine that hosts BridgeDB) is sort of a mess right now

     decision to talk to sysadmin team about container-based deployment solutions

     Blocking of shadowsocks in China

     some background info: Properly configured Shadowsocks servers reportedly blocked in China? · Issue #69 · net4people/bbs · GitHub

     blocking happens by port

     we should check whether our bridges are being blocked by port instead of by IP like we assumed

     if so we might be able to simply change bridge ports instead of IPs for our rotating bridge idea

== Actions ==

== Interesting links ==

Investigating Internet shutdowns through Mozilla telemetry | OONI

     Workshop on NLP for Internet Freedom - ACL Anthology

     Workshop on NLP for Internet Freedom (NLP4IF)

== Reading group ==

     Questions to ask and goals to have:

     What aspects of the paper are questionable?

     Are there immediate actions we can take based on this work?

     Are there long-term actions we can take based on this work?

     Is there future work that we want to call out, in hopes that others will pick it up?
