The top 10 IT disasters of all time
Posted November 29th, 2007 by Andrew Popoff1. Faulty Soviet early warning system nearly causes WWIII (1983)
The threat of computers purposefully starting World War III is still the stuff of science fiction, but accidental software glitches have brought us too close in the past. Although there have been numerous alleged events of this ilk, the secrecy around military systems makes it hard to sort the urban myths from the real incidents.
However, one example that is well recorded happened back in 1983, and was the direct result of a software bug in the Soviet early warning system. The Russian system told them that the United States had launched five ballistic missiles. However, the duty officer for the system, one Lt Col Stanislav Petrov, claims he had a “funny feeling in my gut”, and reasoned if the U.S. was really attacking they would launch more than five missiles.
The trigger for the near apocalyptic disaster was traced to a fault in software that was supposed to filter out false missile detections caused by satellites picking up sunlight reflections off cloud-tops.
