Server migration

We're planning on migrating the zope.org servers to a new facility
sometime in the very near future and would like to get some input on
timing and co-ordinate on DNS changes, since it looks like you all run
the DNS masters. Ideally, I'd like to do this Thursday night, but I
can understand if that's short notice for you, so if there's a time
that'd work better for you, I'm open to re-scheduling. The primary
upside of this move is that we'll be able to provide root level access
to the servers once they've been migrated, something that I know has
been a desire for some time.

Would late Thursday night be acceptable to you? And who do I need to
co-ordinate DNS changes with?

I'll handle it on this end since I'm currently on Central Standard
Time and it'll be easier to coordinate. David, what timeframe Thursday
night are you thinking about?

Generally I like to start at eleven since it's late enough for traffic
(in the US at least) to have dropped to a low point. Would that work
for you?

11 PM Thursday is fine. I'll email you a list of hostnames pointing to
the current ZC server(s), just for information.

Out of curiosity: does this involve the SVN server?

If yes: what's the planned downtime duration gonna be?

I guess you (or Jens) are going to do that anyways, but please make sure to
announce it on zope-dev.

I don't know how long this will take, David may know more. David, do
you have any idea?

Because several of the machines are moving locations physically, it's
going to be about two hours or so. And yes, it does involve the SVN
server. We'll do everything we can to minimize the downtime involved,
but because of the physical move, there's a limit to how much time we
can save.

OK, it's just a matter of telling people beforehand. Out of curiosity,
where are the servers moving to?

Exactly.

Time zone note: 11pm (Eastern, I guess) is around 5am CEST so 2 hours would
leave us at 7 in the morning, after that people start pouring into their
offices and might get affected by the downtime, so it's better they know.
