== Announcements ==


== Discussion ==

    What is the status of activating the snowflake-02 bridge in Orbot?

    snowflake-01 is still pretty much saturated, and snowflake-02 relatively almost unused

    no news yet from Orbot on status of deployment

    latest Orbot release was 2023-01-13

    will add to S96 agenda and discuss in 2 weeks (On March 2rd) if they are not around

    forking obfs4proxy, a new name?

    https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/obfs4/-/issues/40010

    rdsys is using onbasca to measure bridge bandwidth

    https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/merge_requests/76

    bridgestrap is reporing most bridges as non-functional

    looks similar to an old issue: https://gitlab.torproject.org/tpo/anti-censorship/bridgestrap/-/issues/7

    rdsys can handle the situation and will not be a big problem if is not fixed fast


== Actions ==

    meskio will write a survival guide on onbasca

    move the ampcache snowflake fallback forward


== Interesting links ==

== Reading group ==

    We will discuss "Detecting Tor Bridge from Sampled Traffic in Backbone Networks" on March 9

    https://www.ndss-symposium.org/wp-content/uploads/madweb2021_23011_paper.pdf

    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?
