The web sites for The SCO Group, which were beseiged earlier this year by virus-related distributed denial of service (DDoS) attacks, experienced outages of about two hours overnight. Sites affected included www.sco.com, www.thescogroup.com and www.caldera.com.
Dynamically updating performance charts on all the SCO sites are available here.
MyDoom.A programmed several hundred thousand compromised machines to launch a DDoS on www.sco.com on Feb. 1. The site was quickly taken offline, and on Feb. 2 SCO announced that it would use an alternate domain, www.thescogroup.com, as its primary web site for the duration of the event. The attack by MyDoom.A was designed to end on Feb. 12, but the www.sco.com hostname was not returned to service until March 5.
