== Announcements ==
== Discussion ==
no news about obfs4 security fixes, needs to be looked into
Tor Browser will update first: Pick up obfsproxy 0.0.12 (#40416) · Issues · The Tor Project / Applications / tor-browser-build · GitLab
status of snowflake load balancing upgrade
currently staging bridge is handling almost all the traffic
plan to do the upgrade on the production bridge today or tomorrow
then switch the DNS back next week
our metrics are low, the current hypothesis is that the counts are coming from only one of the instances
plan to prevent onion key rotation by making the key files read-only
will try profiling on the staging bridge to help reduce CPU usage of snowflake-server Profile snowflake-server and attempt to reduce CPU usage (#40086) · Issues · The Tor Project / Anti-censorship / Pluggable Transports / Snowflake · GitLab
test deployment of rdsys + bridgedb
next week, will be available to @torproject.org email addresses
aim for production in February
Hetzner networking issue, shall we add it to the timeline
Find more details of the incident and if it has affected any parts of the Tor network
bridgedb and many bridges are in hetzner
== Actions ==
== Interesting links ==
== Reading group ==
We will discuss "Meteor: Cryptographically Secure Steganography for Realistic Distributions" on 2022-02-03
https://dl.acm.org/doi/10.1145/3460120.3484550
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?
