Hi! This is my status report for contract work done in November 2024.
# Snowflake
Snowflake was blocked in Russia in early November. The blocking has since stopped (at least temporarily). I did some analysis using the automatically generated pcaps from our vantage point, and write a few patches to more easily test whether specific proxies or versions of Snowflake can evade the blocking. We'll continue to monitor reachability in case the blocking returns.
My main ongoing task on Snowflake is to look at how we can use Snowflake broker metrics to more accurately detect and respond to censorship events.
I released version 0.9.2 of the webextension and version 2.10.1 of snowflake this month.
We had a major upgrade of the Snowflake broker at the end of November. This required a few followup tasks and debugging. I worked on getting metrics back up and running.
And lastly, a few small logging fixups for Snowflake proxies
# PT library work
After October, there were a few outstanding tasks and issues with the IPtProxy rewrite. This has now been merged and released as version 4.0.0!
# Domain fronting
A few of the remaining Fastly front domains renewed their certificates recently, so we had to update all of our settings to use non-Fastly configurations.
I made some more progress on the meek bridge handover, and updated the bridge to use the new meek.torproject.net and meektm.torproject.net domains.

# Lox
I worked on a few code quality changes last month, including simplifying some Lox tests so they run more easily on laptops.
# Miscellaneous
All the usual merge request reviews and general project maintenance tasks 
I helped with some grant writing and planning early this month.
I also helped debug a tor bootstrapping issue with PTs
