But what if a script checks things like HTTP, FTP etc and if a service fails it takes the server out of the RR-set? The only problem I see is when only a part of the internet fails, so the primary DNS points to location 1 and the secondary DNS points to location 2. I want all users to go to the servers at the same locations. It seems to me Linkproof is not what I'm looking for. The Web Server Director looks more like it, but that comes close to 3DNS of F5 Networks. Money is not the major problem, but I don't want to invest money in stuff I don't need.
