Before you switch your DNS to the cloud hosting, you can preview your domain. In the domain management page, select the “View Website” icon.
You will be directed to a temporary URL that is in the format domain_tld.server.cloudsector.net. (example: kb_sectorlink_com.apache2.cloudsector.net) One thing to note is that some content management systems use the URL from the browser (aka host header) to select the appropriate sections from the database. Wordpress in particular may not display correctly using a temporary URL such as this one. If that case, you can preview your web site with a hosts file.
