+"404" is an HTTP status code indicating that the requested resource could not be found on the server. It signals a broken link or a page that no longer exists, a common encounter in the vastness of the [World Wide Web](/wiki/World_Wide_Web). Often, it leads to a custom [Error Page](/wiki/Error_Page) instead of the intended content.
