I had a site which used a host with 3 nameservers, NS1, NS2 & NS3, I have now moved to one with 2, NS1, NS2 I have added the IP of the new server in NS1, NS2, but what about NS3, it is still setup on the old one, and its been around 24 hours and the site was working earlier however now it seems to be directing sometimes to the old one?
