Ever hear of a nuclear plant being shut down because of a software update? Well is happened. At first it looks like an update gone bad. Indeed it was a design which was flawed. A business system was used to connect to a control system which then went down because of the bad data. After reading the Slashdot article I realized the control system did the right thing by shutting down the nuclear plant in face of the bad data it received since that was the safest thing to do.
So in the end things did not turn out to be so bad after all because of the well designed control system.
