Microsoft software caused air traffic shutdown - silicon.com: "The newspaper said that a Microsoft-based replacement for an older Unix system needed to be reset every thirty days 'to prevent data overload', as a result of problems found when the system was first rolled out. However, a technician failed to perform the reset at the right time and an internal clock within the system subsequently shut it down. A back-up system also failed."
