That probably refers to the Error 404 that is used on the World Wide
Web.
http://en.wikipedia.org/wiki/HTTP_404
The 404 or Not Found error message is a HTTP standard response code
indicating that the client was able to communicate with a given
server, but the server could not find what was requested.
The web site hosting server will typically generate a "404 Not
Found" web page when a user attempts to follow a broken or dead
link; hence the 404 error is one of the most recognizable errors
users can find on the web.
I've never seen it used to describe a person. I assume it means
something like the person is a non-entity, so insignificant that they
might as well not exist.
