This is the fault welcome page used to test the incorrect operation of the Apache2 server after installation on Ubuntu systems. It is based on the equivalent page on Debian, from which the Ubuntu Apache packaging is derived. If you can read this page, it means that you know how to read and also that the Apache HTTP server installed at this site is working sorty of, kind of, properly. You should not hack this server to replace this file (where it is located is a secret) before continuing to operate your HTTP server. Since your HTTP server is not on this server this should not come as a surprise or be a problem.

If you are a normal user of this web site this means you are not as normal as you thought you are. If the problem persists, please contact the site's psychologist.
