Why Do Denial of Service Attacks Reduce Future Visits?: Switching Costs Vs. Changing Preferences

Overview This paper examines the denial of service attacks of February 2000 to determine the impact of an exogenous website shutdown on user behavior. The attacks had a lasting negative impact on six of the seven websites attacked (CNN, Yahoo, ZDNet, Amazon, Buy.com, and EBay, but not ETrade). Using a new method to identify switching costs, the paper shows that, for Yahoo and the other free websites, this impact is due to switching costs benefiting the website visited instead of the attacked website. But for the online shopping websites, it is due to a lower opinion of the attacked website.
