Just a quick question on how you guys set up your clustering. Do you have ALL of your servers clustered with each other. I have seen some load issues when it was set up like this (from dnsadmin). To cut back on that, what I'm thinking is to have a main server that shows all servers within the cluster. I then sync all other servers with that main server, but not together. So, each 'sub' server talks with the main server but the 'sub' servers do not talk with each other. In theory, all DNS records should still be up to date as information is passed from sub server to main server and then to the other servers. Does anyone see a problem with this set-up?
