Software Upgrade Crashes UK Air Traffic Control System

pitpe writes "Earlier today the computer system controlling most of the UK's airspace failed, after tests in preparation for an upgrade failed. The original failure occurred at the West Drayton centre, which is an old (70's) system, as opposed to the new system at Swanage, which has had its own problems. A system wide reboot to fix the system resulted in the entire system being taken down temporarily."
