Due to a stupid decision by cPanel to allow only 64-bit OS on their DNS Clusters, we will be migrating our current nameserver cluster to 64-bit OS. This shouldn't result in any downtime. The NS4 server will be migrating to an entirely new rack and IP address (with a different bandwidth blend). Unless you're using the IP address for NS4, the change should be transparent. The Teamspeak migration should also be transparent, aside from a reboot and IP change. If you are using the IP, it will need to be changed.
