Changing server IP address

[Kevin Darcy]

The root and TLD servers don't pick up glue records automatically; in
addition to changing the A record in your zone, you need to update your
"host record" through your registrar. Until that change is processed,
other nameservers will continue to go to your old server some of the time.
