Without slow start, load balancers have been known to cause many problems. One famous example is what happened to the CNN.com web site on the day of September 11, 2001 terrorist attacks. So many people tried to access CNN.com that the backends become overloaded. One crashed, and then crashed again after it came back up, because the naive least loaded algorithm sent all traffic to it. When it was down, the other backends became overloaded and crashed. One at a time, each backend would get overloaded, crash, and become overloaded from again receiving all the traffic and crash again.

As a result the service was essentially unavailable as the system administrators rushed to figure out what was going on. In their defense, the web was new enough that no one had experience with handling sudden traffic surges like the one encountered on September 11th
