Thanks William. But what about visitors to the site? Would some go to
one box and some to the other? There are two ways that this *might*
work.
1. Load balancing - albeit in a non controllable way. i.e. half the
visitors go to ns.domain1.com and half go through ns.domain2.com. (Maybe
not half, but 'some' proportion)
2. Redundant - ns.domain1.com is down so requests go to ns.domain2.com
And what about e-mails? Could you get a case where an e-mail lands in
the popbox on the backup server and the client can't pick it up until
his machine decides to take the route to the second machine?
