How long does it take for a new website name to be active?
Once you have purchased your name, it may take a couple of hours for your site to be linked to your new name and its SSL certificate.
This is because Domain Name servers around the world have to register the update.
After this period, you can publish your site, and your name, site, and https will all be working together.
