Snowflake =========

* Published Snowflake WebExtension 0.2.0, enables metrics on different types of proxy implementation.

* Fixed a data race in the Snowflake broker. https://bugs.torproject.org/32576

* Started collecting metrics on Snowflake proxy types at the broker. https://bugs.torproject.org/31157

* Continued investigations of Snowflake health and blocking in China. https://bugs.torproject.org/32657

* Expanded Snowflake test coverage. https://bugs.torproject.org/29259

GetTor ======

* Fixed distributor update script to prevent filling up disk space on the GetTor machine. https://bugs.torproject.org/32712

Obfs4 and bridges =================

* Published obfs4 bridge docker image version 0.3: https://community.torproject.org/relay/setup/bridge/docker/

* Added a new default bridges located at the University of Minnesota. https://bugs.torproject.org/32547

* Added a cache to bridgestrap, so scan results can persist across restarts.

BridgeDB ========

* Started porting BridgeDB to Python 3. Numerous unit tests now fail because strings and bytes are strictly separated in Python 3. This will require significantly more work. https://bugs.torproject.org/30946

* Summarised an upcoming project deliverable in which we will build a feedback loop between BridgeDB and OONI. OONI wants bridges to test and BridgeDB wants to know where its bridges are blocked. We should get the two to talk to each other. https://bugs.torproject.org/32740

* Worked with Karsten to have some of our BridgeDB metrics published on Tor Metrics. The graphs are now online at https://metrics.torproject.org/bridgedb-transport.html and https://metrics.torproject.org/bridgedb-distributor.html. https://bugs.torproject.org/32135

Miscellaneous =============

* Continued talking to our admins to unify our monitoring infrastructure using both Nagios and Prometheus. https://bugs.torproject.org/31159

* We discussed the idea of making our bridge authority more resistant to outages by setting up two physical instances behind a single, "virtual" IP address. https://bugs.torproject.org/31878#comment:3

Outreach ========

* On January 9th, Philipp will give a talk on censorship resistance and Tor at FH Hagenberg in Austria: https://twitter.com/torproject/status/1208102010832277504
