We are not going to add all the variations of the mirrors'
domain names. You can make the bottom text "properly" work
by setting your ServerName in the vhost setup cz.php.net, and
setting www.php.cz as an alias. It won't affect the behaviour
of the mirror looking from outside, but our clever code will
recognize your mirror as cz.php.net even if someone uses some
other domain name to acess it [any other domain name to be
precise].
