Comment:

 I got the IPv6 situation sorted out. (Just needed a different prefix.)
 Here's the information. After we've switched to this new host, I'll update
 the SSH fingerprints in
 [[org/teams/AntiCensorshipTeam/SnowflakeBrokerSurvivalGuide]].

 {{{
 37.218.245.111
 2a00:c6c0:0:154:4:d8aa:b4e6:c89f

 RSA:  2048 SHA256:dp0Xo/oN1qZfMuZnqgKEbeOsbU2qpDR60B5MLIRaAgg

 Now the question is what to do about handling the migration. We can talk
 about this at the next meeting on Thursday. All that's needed is to point
 the following DNS names to the new IPv4 and IPv6 addresses:
  * snowflake-broker.bamsoftware.com
  * snowflake-broker.freehaven.net (currently a CNAME for snowflake-
 broker.bamsoftware.com)
  * snowflake-broker.torproject.net
 About logs, I'm thinking we just let the log files happen in parallel on
 the old and new hosts. Then after we've made the switch, we check the old
 logs for sanitization and publish them. Logs we publish in the future from
 the new broker will partially temporally overlap those from the old, but
 that should be no problem.

 I've copied over the contents of people's home directories.
