 Replying to [comment:13 micah]:
 > I think that the IPv6 address for longclaw should be removed in the
 source code. It was only a temporary address that I setup on teor's
 request for testing and never was meant to be something that stuck.
 Additionally, longclaw will be moving to a new location, so its ipv6
 address will go away then (I'm unsure when it will get a new one)

 See my branch longclaw-ipv6-028, which implements this change. The address
 was added in 0.2.8, so it only needs to be backported that far. We don't
 need to worry about clients here: 0.2.8 and later have plenty of fallback
 directory mirrors on IPv6, which isn't on by default anyway.

 > as well as its ipv4 address.

 Now, that will be more interesting. I assume you mean both the hard-coded
 IPv4 address, and the one in the consensus? Have they changed at all since
 longclaw was added in 0.2.6.2-alpha / 0.2.5.11 / 0.2.4.26 ?

 Here's what clients will do:
 * Clients with a consensus will use whatever address longclaw signs in its
 relay descriptor
 * Clients without a consensus:
   * 0.2.8 and later try multiple authorities without waiting for failures,
 so they will be fine
   * 0.2.4, 0.2.6, and 0.2.7 are no longer supported:
 https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorReleases
   * for 0.2.5, I will pull out the email that arma and I worked on last
 time we changed directory authority details, and re-post it to tor-project
