== Announcements ==
*
== Discussion ==
* https://trac.torproject.org/projects/tor/wiki/org/teams/AntiCensorshipTeam/NGOBridgeSupport
* New wiki page on how to walk NGO through the process of distributing private bridges
* How can we make this process easier? See: https://bugs.torproject.org/28015
* "Moat secret password" is a neat idea
* How should we manage our private bridges?
* So far, it's just a CSV. We want to keep track of who got what bridge and when.
* When should we switch over to the new IPv6-having Snowflake broker? See https://bugs.torproject.org/29258#comment:11
* Design considerations for a new service that tests bridges:
* https://trac.torproject.org/projects/tor/ticket/31874#comment:2
* Discuss workflow for gettor
* Sponsor 28: status? anything to report?
* we have a prototype of new obfs4 flow obfuscator: https://trac.torproject.org/projects/tor/ticket/30716#comment:16
* snowflake is moving forward
* Sponsor 30: how are we doing?
* https://trac.torproject.org/projects/tor/ticket/31274
* A1- Create an evaluation framework for bridge distribution and selection methods.
* https://trac.torproject.org/projects/tor/ticket/31281
* A1 - Improve documentation on how to set up a bridge server and different pluggable transport bridge servers.
* A2 - Create scripts and configuration code for setting up a bridge on cloud providers to make it easier for operators to launch a new bridge.
* https://trac.torproject.org/projects/tor/ticket/31282
* A2 - Define which censorship scenarios we are going to address.
* Should we increase the default Snowflake poll interval? A lot? Last I checked, the broker was getting like 40 requests/second, which is way way more than we need.
* Note: https://metrics.torproject.org/collector/archive/snowflakes/ since the release for windows, client usage has gone up by 5-10x but we still have orders of magnitude more idle snowflakes
* dcf wonders why there's no apparent change in the bridge statistics https://metrics.torproject.org/rs.html#details/5481936581E23D2D178105D44DB6915AB06BFB7F
* We could use a dedicated build server for the anti-censorship team to test tor-browser-build.git builds.
* It's too big to build comfortably on a development PC/laptop, so devs are getting their own VPSes.
* Requirements: 8 CPUs, 200 GB+ disk.
* Could be shared with other teams.
* Snowflake: Support portal and tb-manual documentation updates
