Page Not Found

Start looking around on the Internet and it's not too long until you get an error page.  It often says: "This page cannot be found" or "HTTP Error 404 Page Not Found".

This means that the server (the computer on the Internet) cannot locate the page that you asked for.

This can happen for a number of different reasons.  Many people immediately assume that they've done something wrong but that is not necessarily the case.

Page Not Found Example

Possible Reasons for Page Not Found

  • A fluke...a brief mix-up between computers. Sometimes they just get confused. Refresh the page using the refresh button in the standard toolbar.
  • Misspelling or mistyping. Look for mistakes in the address. Did you hit the comma instead of the period? Is the address spelled correctly?  Website addresses are like phone numbers, you don't expect to get the right person if you dial even one number incorrectly.
  • The web creator or owner may have changed, moved, or deleted the page you are looking for. Even if the web site exists, old pages may be removed or the name may have changed - and you receive an error when you look for the original.
  • Old links may be inaccurate. When one web site links to another, the links must be constantly checked and updated for accuracy. This doesn't always happen. Some websites, created years ago, are not maintained. Suppose they link to sites that no longer exist? When you click to follow such a link, you receive an error because the non-existent page cannot be found.
  • The server computer could be having problems. If you know the address is correct, try again later.

Here's a site that explains several steps to try when you get a 404 error.
