While there is currently no way to un-publish your website from the internet, there are two things you can do to discourage people from visiting your site.

  1. If you've mapped your domain to your website, you can remove the mapping until you're ready to go live.  To do so, visit the Domain Mapping menu in your website dashboard and click the trashcan icon on the far right of the row where your domain name is listed.
  2. In the Site Settings menu, there is a selection for "Search Engine Visibility", make sure that is set to Development Mode.
