On February 7, 2000, Internet mainstay Yahoo.com experienced a lengthy service outage. What became clear over the following hours was that the site had been victimized by a distributed denial of service (hereafter abbreviated to “DDoS”) attack from hundreds of geographically dispersed Internet-connected machines sending millions of request for service packets. Over the next few days, additional attacks were launched against six other major Web sites, among them some of the favorite sons of the then-burgeoning e-commerce revolution. The ultimate victims were Yahoo.com, Amazon.com, Buy.com (attacked a mere hour after their initial public stock offering), ZDNet.com, E-Trade.com, eBay.com, and CNN.com. According to the Yankee Group, estimated costs of the attack totaled $1.2 billion cumulative and the attack on Amazon alone cost between $200,000 and $300,000 per houri. Losses of customer goodwill, corporate reputation and public trust may have been even greater.
