hiro: (gettor days are Thursday)
This week (2019-06-27):
* Sent "call for new obfs4 bridges" email to tor-relays at tp.o.
* One person contacted me directly after setting up a new bridge. They thought the instructions worked very well.
* Worked on #30931 so arlo, dcf, cohosh, and I can all manage our snowflake webextension
* Arlo already submitted the extension to Firefox and Chrome!
* Worked with more operators of broken obfs4 bridges.
* Sent ten of BridgeDB's unallocated obfs4 bridges to activist for manual distribution.
* Lots of work on #30441, to stop BridgeDB from handing out offline bridges.
* The problem may have fixed itself?
* Blacklisted 53 broken obfs4 bridges.
* Added debug log messages and discovered bot that's scraping bridges.
* Brainstormed obfs4 improvements over at #30716.
* For now, we decided to understand the "long tail" of network traffic first (#30986)
* Once we have a better understanding of the long tail, we'll continue with obfs5
* Attended RACE call in which we discussed all of this.
* Filed #30946 to port BridgeDB to Python 3.
* Published blog post that introduces the anti-censorship team and our Sponsor 19 report.
* Lots of help from gaba and stephw!
* Had a brief look at the popularity of an active probe's cipher suite over at #30500.
* Caught two probes that had a different cipher suite; one quite common, but not the other
* Pushed a feature branch for our BridgeDB metrics (#9316) which is now in 'needs_review'.
* More RACE work (PT spec and network trace "long tail")
* Try requesting different types of bridges from bridges.torproject.org and let me know if you got 0 bridges.
