If you have a new domain name, you must change the name servers so they point to HDWEBPROVIDER™. If you have a reseller account, you must point the domainnames to your custom ns1 and ns2.
Name server or record changes usually take 24 to 72 hours to start working. This phenomenon is known as international propagation. Because of propagation, not all visitors will follow your new name servers to your new hosting account; some visitors will continue to follow your old name servers to your old hosting account.
How quickly visitors follow the new name servers depends on their physical location, internet service provider, and some luck; it is not something HDWEBPROVIDER™ has control over. Once propagation is over, your site will be appearing on our network and your email will be fully functional. (with and without www.)
There is no positive way to tell when propagation has completed. During the first 48 hours, even if you see your site online, your next door neighbor might see the site on the old server, or another website. If you still have issues with your name servers after 72 hours, please submit a ticket to the 24/7 support center.
