Instead, I would move one server, wait a week or two, then move the
second server. This gives the clients a chance to notice the change,
and doesn't require us to run a third server. Brief chronology:
1) advertise the change. Have athena put all four addresses in their
CellServDB.
2) wait two or three weeks.
3) move one server (preferable ronald-ann, so rosebud stays the
primary)
4) wait a week or two.
5) move the other server
All addresses are being advertised now... so we could move both.
For me to advertise it to the world, I need a predefined time (and I
only get to do it once; they will not appreciate multiple updates, nor
will they appreciate incorrect IP addresses).
The Athena side isn't nearly as difficult as telling the world.
