All domains, as with any provider around the world, cannot guarantee full use of a domain name immediately after purchase. The process of the domain name becoming live, involves it passing through the entire web and in effect registering itself. The default time period is set around 24 to 72 hours for this, although we have no control over this figure. Depending on web traffic though, it can be significantly less than this. Obviously, although out of our control, it often takes around 3 hours or so.
