Name server changes usually take 24 to 72 hours to start working. This
phenomenon is known as 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 IspNow has control over. Once propagation is over, your
site will be appearing on our server and your email will be fully
functional.
There is no positive way to tell when propagation has completed. During
the first 72 hours, even if you see your site on the new server, your
next door neighbor might see the site on the old server.
