Kind of, except both machines are on 2 different ISP, in different states. At ApacheCon, I described how I have a server in Oregon and a server in Florida, and I have a monitoring program that does a dynamic DNS update when one of the hosts goes down. The individual described that what they are doing is something to do with BGP, in which they have multiple servers in different countries, all with the same IP address. Traffic is routed to the nearest logical server, until one goes down, then the traffic is routed to the nearest logical server that is still up. That is what I am wanting. Since I didn't get the person's contact information, I am trying to figure out how to do it myself. Sincerely, Rick Duvall ----- Original Message ----- From: "Marc G.
