404 Not Found

Description

The HTTP 404 Not Found response status code indicates that the server cannot find the requested resource. Links that lead to a 404 page are often called broken or dead links and can be subject to link rot.

A 404 status code only indicates that the resource is missing: not whether the absence is temporary or permanent. If a resource is permanently removed, use the 410 Gone status instead.
