Wikimedia Bugzilla is closed!

On the advanced search page (http://bugzilla.wikimedia.org/
query.cgi?format=advanced) there are some links the point to 
http://bugzilla.wikimedia.org/queryhelp.cgi (for example, 
'relative dates'). However, I get an 404 error:
-------------
Not Found

The requested URL /queryhelp.cgi was not found on this server.

Additionally, a 404 Not Found error was encountered while trying 
to use an ErrorDocument to handle the request.
-------------
Using Opera 8.02 build 7680, on Windows 2000 SP4.
Intenet Explorer also gives an 404 error, but this is the 
standard 'Not found'-page from IE.
