Hi www-validator!  As I'm not subscribing the list please CC. me.

I noticed that http://validator.w3.org/check?uri=referer lead to the
following content
`````
Not Found

The requested URL /check was not found on this server.
------------------------------
Apache/2.2.22 (Debian) Server at validator.w3.org Port 80
`````
while  http://validator.w3.org/check work normally, is it something valid
to file on BugZilla?
