Name server changes typically take between 1-48 hours to fully propagate. There are also several factors dealing with browser/DNS caching. Unfortunately, this is completely beyond our control. You can read much more on this process on our Name Server Manager support page. Rest assured that there are absolutely no delays on our end. Your name server change will already be reflected in WHOIS, and the change already made at the registry which is the extent of our involvement in this process. It is very likely that your changes will not appear to be working for 1-48 hours.
