Case Study: “The Worm – Episode 1”

The Department had an Application Server running an extremely Critical Application, which processed hundreds of requests a day. We were informed that the Critical Application had become non-operational a few days earlier, and that a large number of service recipients had begun to queue outside the Office as a result.
