I have changed my domain name servers but still the site is running on the old host. I have checked the settings at my domain control panel and it says that the changes have been made. I have checked my domain whois on two different whois sites. One site shows me the old name servers while the other shows my the new name servers. Can any body help me on this problem?
Check out your site on www.dnsstuff.com. You can find if there are any DNS related problems. If it is ok, just wait out for 24 hours till the DNS change propagates.
Do all the Root Name servers (13 for .com) show the old server? If your Domain control panel shows the changed servers correctly, you should be ok.
