If you are seeing this page after you have already uploaded your Web site, here are some possible causes:

Be sure you have uploaded your site files to your /public_html directory.

Make sure you named your home page either index.htm or default.htm.  The system looks for a file with either of these names by default if a visitor enters the URL of your site without any specific filename (e.g. http://www.xyz.com or http://xyz.com).
