I don't think it would be that hard to launch all zombie machines within 60 seconds of each other. Heck, run ntp on them all, and set the DoS time. They'll all start within the second.

SCO press release on DDOS attack

Ok, how about this:

The IP address of ftp.sco.com is 216.250.128.13. The IP address of www.sco.com is 216.250.128.12 - which is the one that is "attacked".
I do not think it is possible for the above two to be on seperate subnets, because the "12" would then be a network address and an invalid machine IP, (and as the subnets would only consist of 4 IP addresses you could only have one machine per subnet making it pointless anyway). - So it is safe to assume they are on the same network.
ftp.sco.com (the .13 address) is staying up all through the "attack", so the "attack" is not swamping the network there.
Linux has a means of dealing with SYN attacks by using "SYNCOOKIES". They are fast and easy to implement. This would negate the effect of the attack enabling them to keep the website up. It is difficult to believe that SCO, or their web hoster, do not have the technical expertise to implement that.
All in all the "facts" do not make sense here. Either SCO (or the web hoster) is incompetent, or they are lieing.

"All in all the "facts" do not make sense here. Either SCO (or the web hoster) is incompetent,"

I don't think it would be their web host. And to be honest, Caldera Open Linux had a reasonable reputation for security, which should have meant that those that produced the distribution understood how to configure it... Perhaps all the technical people have been laid off and all they have now are executives with bad hair and lawyers.
