How do I update nameservers for my domain?
If your domain was registered through GlobalFront, then to update nameservers for your domain, please log into Global Domain Control Panel, click on “Nameservers” button, select “Edit/Update Nameservers” option, and enter new nameserver information. Please note that it may take upto 24-72 hours for the effects of nameserver updates to be reflected across the net. This is the standard delay for propagation of registry updates.
