Error 404

When we go to the site, but there is no such page, this is error 404.
You get to a specially created page 404 and there you are informed about the error and perhaps you specify the address or use the search. Periodically, something is changing, the largest services cease to exist, not that the pages.
Someone on the site of the specially created page 404 directs visitors to a visitor who has entered an incorrect or outdated link to the site map or to the start page of the site.
