The unexpected and unprecedented demand for news generated by the events of September 11 quickly drovealmost every news web site into the ground, including CNN.com. In the span of 15 minutes the demand for our site increased by an order of magnitude. With only 85% availability, we still served over 132 million pages on that day, nearly equalling our site's all-time high. On September 12, we shattered any previous site records with 304 million page views. This talk will tell the story of CNN.com and the team that worked so hard to meet the unbelievable user demand. One of the biggest challenges faced by the team was induced by cascading failures, so that increasing capacity alone was not sufficient to resurrect the site. The talk will conclude with a discussion about the relevance of this experience to anyone who runs a Web site.
