If you're expecting to see some other page here, probably your
DNS server is out of date (or your ISP's DNS server is out of date).
The internet is fine, and the site you were looking for is fine - it's just hosted over at our new machine now.
This is really shibboleet.slackbuilds.org, and it's a VPS provided by Omnicity (see below), but it's on the same IP address that the old (dead) cardinal was on, so we kept the old links working...
Thanks to Adam Kennedy and Omnicity for providing colocation and bandwidth.
