'www.sco.com' no longer resolves. SCO turned this off on their own
yesterday. Other host names ('sco.com','www.caldera.com') still resolve
to the original IP address (220.127.116.11).
The page does respond reasonably fast if one of the other URLs is

Some ISPs may have turned off 'www.sco.com' early on for "self
preservation". I don't think SCO has a case against any of these ISPs,
as SCO doesn't have a contract with them. Only users of these respective
ISPs may have a case depending on how the user agreement is written.
Overall, it is probably reasonable for an ISP to block a smaller site
like www.sco.com if this will protect the ISP's network.
So far, I haven't heard anything about ISPs actually experiencing
problems. However, different ISPs may be affected in different way
depending on subscribers and network layout.
