== Announcements ==

* bridges running 0.4.7.x (EOL) were rejected by Serge: https://lists.torproject.org/pipermail/tor-relays/2024-June/021678.html

== Discussion ==

* what's the plan for: https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/142 * we've lost a lot of webextension snowblake proxies, proably due to people not noticing the new consent page * luckily the rise in orbot proxies (probably from the v17 rollout) makes this not as urgent as it otherwise might be * cohosh is working on this issue

onyinyang: 2023-06-06 Last week(s): - Finished key rotation implementation - Working toward building tor-browser with lox-wasm binary to help out with integration work as needed - Preparation for MSR talk Next week: - MSR talk - Work on outstanding milestone issues: https://gitlab.torproject.org/tpo/anti-censorship/lox/-/milestones/1#tab-iss... - prepare for end to end testing of the Lox system with browser integration Later: - begin implementing some preliminary user feedback mechanism to identify bridge blocking based on Vecna's work - improve metrics collection/think about how to show Lox is working/valuable - sketch out Lox blog post/usage notes for forum (long term things were discussed at the meeting!): https://pad.riseup.net/p/tor-ac-community-azaleas-room-keep - brainstorming grouping strategies for Lox buckets (of bridges) and gathering context on how types of bridges are distributed/use in practice Question: What makes a bridge usable for a given user, and how can we encode that to best ensure we're getting the most appropriate resources to people? 1. Are there some obvious grouping strategies that we can already consider? e.g., by PT, by bandwidth (lower bandwidth bridges sacrificed to open-invitation buckets?), by locale (to be matched with a requesting user's geoip or something?) 2. Does it make sense to group 3 bridges/bucket, so trusted users have access to 3 bridges (and untrusted users have access to 1)? More? Less? theodorsm: 2023-06-13 Last weeks: - Writing on my thesis Next weeks: - Add hook to pion/webrtc so it can be used in snowflake, currently waiting on new pion/dtls release - Add randomized fingerprints - Writing my thesis Help with:
