I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

As you cannot change the actual address in the request (the URL in the email), you have to have some sort of fall over support with your ISP.

I would talk to them.

A few things.

1 - Sync. Make sure both servers are upto date. Any changes you make to one server have to be mirrored.
2 - Separate web and DB servers. This allows a cluster of web servers to work with a cluster of DB servers. Syncing each type is done within the cluster.
3 - Buy this service from someone like akamai.

If you have real time access to the DNS data for the 2 domains, then you could have a little script running which examines the state of domain A and if it cannot find it, alters the DNS to domain B.

This should alert you or your admin people to take a look at the problem.

I'd not really expected a good solution as I'd researched this prior to asking
Even with a script to change the DNS it would be down for the time it took to propagate
Possibly a way using dynamic dns but still not what we were hoping for
(I could ask for winning lottery numbers too couldn't I)
Thanks for the comments though
