Flights in and out of Switzerland were suspended for hours as Swiss airspace closed because of a computer failure at air traffic control service, Skyguide. Geneva and Zurich halted early flights but Geneva airport announced air traffic was gradually resuming. Skyguide said a technical malfunction in the early hours of today meant Swiss airspace had had to be closed to traffic for safety reasons. Some flights were being diverted to Milan in northern Italy.
Skyguide spokesman Vladi Barrosa confirmed that the problem appeared to be a hardware fault, noting that they did not believe their system had been hacked. The company later announced that the technical malfunction at Skyguide has been resolved and airspace closure lifted later this morning.
