I wonder how much SCO would really be down, or if operators just
panicked, and blocked it...

>From two different parts of the internet (one was tracerouting through
psi.net and the other through alter.net), traceroutes to die just prior to us.xo.net, but to either *.11 or *.13
work fine for many more hops...

Also, it looks like www.sco.com was just recently taken out of DNS
from SCO's name servers...  However sco.com still points to the IP,
but it appears blocked...
