it's a problem and comes up occasionally here. I think it
may be discussed in the HOWTO (I should know, but I've

There is no cheap solution. If you have a two pairs of
directors in separate locations, then the data centers have
to cooperate (usually the same company) and they have to do
fast DNS updates.
