onyinyang: 2023-08-15     Last week(s):         - vacation         - continued with key rotation integration work

Next week:         - continue with key rotation integration work         - add trusted invitation logic to tor browser integration: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42974         - Work on outstanding milestone issues:             in particular: https://gitlab.torproject.org/tpo/anti-censorship/lox/-/issues/69             - key rotation automation

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?
