Not sure is the terminology is correct for what we want to do, but here is what we are looking to do..

We have two web servers one is on the East Coast one on the West Coast. We replicate the contents of the West Coast Server to the East Cost Server every hour or so.  If we have an outage on the West Coast.. the only way people know to get to the other site is if they already know the address.  Is there anyway to do this automatically?

Thx

There are two steps to this.  The first is to make sure your primary server is replicated on your secondary server.  It appears you are already doing this.

The second step is to have a DNS failover system that monitors your primary server and, if it goes down, begins routing traffic to your secondary server.  ZoneEdit.com offers DNS failover as on option with their DNS service, but a higher-end option might be DNS Made Easy's DNS failover service (see www.dnsmadeeasy.com/s0306/prod/dnsfo.html).

If you are running your own DNS servers, you can probably configure them to provide failover service (depending on what you are using), but remember that if your DNS server and primary web server are on the same machine they'll both go out at the same time.
