Currently I am running three servers, located in three different data centers. Each server is set up with it's own name servers, for example, server 1 has the name servers ns1.domain.com and ns2.domain.com, server 2 has the name servers ns3 and ns4.domain.com, etc. This works out pretty well except when I need to move a customer from one server to another, then not only do I have to move the account, but change the customers name servers as well. Does anyone have any other suggestions on a better way to set this up? I would love to have one server handle everything, but I'm not sure If I can do this since they are all in different data centers.
