== Announcements ==

- Let's start thinking about the Tor meeting in July and if this team needs any private session (maybe roadmap & retrospective for the team?) https://trac.torproject.org/projects/tor/wiki/org/meetings/2019Stockholm/Dai... .

== Discussion ==

* We just retired 19 default bridges. Where should we get new ones? * We're left with: https://trac.torproject.org/projects/tor/wiki/doc/TorBrowser/DefaultBridges * Team Cymru may be willing to help again, but we should decentralise our operators. * University contacts? * Roger is asking what the current state of IPv6 and Snowflake because a research group wants to run a Snowflake test on a large IPv6 block. (ahf: 11/5) * See kat5's "help with" * Should we do #5304 as part of s19? The change seems trivial to do, but might be a good idea? Propagating OutboundBindAddress to PT's.

[Announcement I forgot] Please spread the word about the Mozilla Research Grant for Tor https://blog.torproject.org/mozilla-research-call-tune-tor-integration-and-s...
