* Roadmap: Development · Boards · Anti-censorship · GitLab
* The anti-censorship team's wiki page:
* Home · Wiki · The Tor Project / Anti-censorship / Team · GitLab
* Past meeting notes can be found at:
* The tor-project Archives
* Tickets that need reviews: from sponsors, we are working on:
* All needs review tickets:
* Merge requests · Anti-censorship · GitLab
* Sponsor 28
* must-do tickets: Sponsor 28: Reliable Anonymous Communication Evading Censors and Repressors (RACECAR) · The Tor Project · GitLab
* possible tickets: Issues · The Tor Project · GitLab

* Sponsor 139 <-- hackerncoder, irl, joydeep, meskio, emmapeel working on it
* Riseup Pad
== Announcements ==
*
== Discussion ==
* is there any proposal to encode bridges into human-memorable form? like a list of words?
* people have trouble pasting in the bridge lines (fail to get the entire line for example), and support wants either:
* something that is easier to copy and paste, or
* and easy way to verify that the line was pasted correctly (visual checksum or similar)
* bridgemoji are meant to serve this role
* gus will open an issue for user research of different options (QR code, sequence of words, others)
* snowflake fallback from domain fronting to amp cache, how/whether/when/etc to implement (Broker side channel fallback mechanism (#40250) · Issues · The Tor Project / Anti-censorship / Pluggable Transports / Snowflake · GitLab)
* arma is going to check how hard would be to change c-tor to only connect to two bridges instead of all of them at once. So maybe we can duplicate bridges with domain fronting and amp cache.
There is a patch which implements this idea:
Let bridge users choose to only reach their first working bridge (#40578) · Issues · The Tor Project / Core / Tor · GitLab
But see also the caveats on
Broker side channel fallback mechanism (#40250) · Issues · The Tor Project / Anti-censorship / Pluggable Transports / Snowflake · GitLab
* we need to check the consecquences of using amp cache, and if we are ok having half of our users using it
* Three possible options:
* multiple bridge lines with different configurations, having multiple bridges with different fingerprint or fixing tor to allow multipe bridgelines with one fingerprint
* different definitions in TB for domain-front and amp-cache so users can pick
* snowflake client does control the fallback, maybe by passing flags with what to fall back to
* use ampcache for snowflake in IR?
* Blocking of cdn.sstatic.net by SNI in Iran, 2023-01-16 to 2023-01-24 (#115) · Issues · The Tor Project / Anti-censorship / Team · GitLab
* Use ampcache for snowflake in Iran (!13) · Merge requests · The Tor Project / Anti-censorship / rdsys-admin · GitLab
* our domain front for both snowflake and circumvention settings was blocked in Iran for 9 days
* Packet loss resulted in performance issue for snowflake in China
* Analysis of speed deficiency of Snowflake in China, 2023 Q1 (#40251) · Issues · The Tor Project / Anti-censorship / Pluggable Transports / Snowflake · GitLab
* snowflake fails to bootstrap in the vantage point due to packet lost
* shellikhoo is investigating it
* (from ahf): do we have an idea about how many C tor modifications that needs to be reviewed before s28 is wrapped up? Purely so we can plan this for take-in.
for next week:
* Conjure is in nightly versions of Tor Browser now, an update on how it's going and the roll out plan
== Actions ==
* We should make a ticket for pion to cache its stun answers when possible, because right now it surprises us by asking way more stun questions than it actually needs to.
* We might want to be able to spin up our own stun servers, on our own ip/port, for debugging. We should talk to TPA about that goal at some point (not urgent).
* Roger will look more at Let bridge users choose to only reach their first working bridge (#40578) · Issues · The Tor Project / Core / Tor · GitLab ("only contact the first few working bridges on your bridge list") and plan to have a sense of whether it will be an easy hack or a hard one, for next week.
== Interesting links ==
* Snowflake (software) - Wikipedia
== Reading group ==
* We will discuss "" on
*
* 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?
