Information regarding site locations is recorded on DNS tables or nameservers.
The update of these records is referred to as propagation . Propagation normally lasts 48-120 hours. During this propagation period some ISPs will still point visitors to the web site located on your previous web host's servers while other ISPs, that have already updated their DNS Tables, will point your visitors to the web site located on your new web host's servers. This is usually a frustrating and confusing time for the site owner and visitors as well. Inc. You may not duplicate or redistribute in any form without prior written consent.
