Anti-censorship work meeting pad --------------------------------
Next meeting: Thursday October 21st 16:00 UTC
Weekly meetings, every Thursday at 16:00 UTC, in #tor-meeting at OFTC (channel is logged while meetings are in progress)
== Goal of this meeting ==
Weekly checkin about the status of anti-censorship work at Tor. Coordinate collaboration between people/teams on anti-censorship at Tor.
== Announcements ==
== Discussion ==
Unifying bridge/broker domain names? All these different names point to the same place
proxy uses snowflake-broker.bamsoftware.com and snowflake.bamsoftware.com
webext uses snowflake-broker.freehaven.net and snowflake.freehaven.net
client uses snowflake-broker.torproject.net
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowf...
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowf...
This is merged, not deployed yet.
New 'Run a Bridge' campaign - November 2021 (S96): https://gitlab.torproject.org/tpo/community/relays/-/issues/24
will offer T-shirt rewards
One positive outcome of such a campaign would be to encourage people to join discussion groups and support one another in bridge operation
in november forum.torproject.net will be official
we have already met the goal for new snowflakes, > 12,000 unique snowflake ips per day
what is the status of non-nat snowflake bridges?
from the prometheus metrics it looks like we're doing okay
we have many more idle snowflakes for clients with restrictive NATs than denials
ggus will need help tracking, testing, and counting new obfs4 bridges during the campaign
What happened in the presentation yesterday, "How to Make a Blizzard: Recruiting Snowflake Proxies and Rewarding Resource Sharing"?
Calyx ran a campaign to recruit snowflakes (~50) with T-shirt incentives
PT spec standardization discussion from Pluggable Transport Implementers' Meeting this week
https://github.com/Pluggable-Transports/Pluggable-Transports-spec/blob/70bc1... proposals that are candidates for being added to the next version
The EVENT proposal is an older version of what became STATUS in Tor's spec
PT spec maintainers may get in touch for discussion and updating
The logging proposal is for a different purpose, a common API and log levels
PT standardization and Tor
discussion at PTIM about the difficulty of fitting diverse transports into one mold, is it necessary?
"at some point when we do PT's for Arti, i think we should take a bit of a brutal look of how the interaction between the host and its PT can be made better, but in a way such that we can still execute PT processes, but also load them as libraries"
== Actions ==
== Interesting links ==
https://github.com/Pluggable-Transports/Pluggable-Transports-spec/blob/70bc1...
proposal for a logging interface in the PT API, somewhat relevant to the discussion about STATUS from https://lists.torproject.org/pipermail/tor-project/2021-October/003194.html
https://github.com/Pluggable-Transports/Pluggable-Transports-spec/blob/70bc1...
proposed EVENT message, this is actually an earlier version of what became STATUS in Tor's pt-spec

== Reading group ==
We will discuss "Characterizing Transnational Internet Performance and the Great Bottleneck of China" on 2021-10-28
https://censorbib.nymity.ch/#Zhu2020a
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?
== Updates ==
