I am curious about this for my own personal reference and information.

I changed my hosting company 8/29/09, during the file transfer I updated the DNS Server IP Addresses at Go-Daddy who my domains are purchased with and yes I am on a dedicated server.

Now I ran my sites name through da whois:
Domain Information
DNS Servers NS1 and NS2 still show my sites old dedicated server IP addresses.

Geo Information
Is showing the correct IP address and data center's location.

When will this change to the correct information or is there something else I need to do to complete this? I completed the A entry when my server prompted me to after the file transfer.
