== Discussion ==

* https://trac.torproject.org/projects/tor/wiki/org/teams/AntiCensorshipTeam/N... * 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/5481936581E23D2D178105D44DB69... * 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
