Switzerland Reopens Airspace after ‘Technical Malfunction’

Switzerland reopened its airspace Wednesday after a brief closure for safety reasons because of an unspecified “technical malfunction,” authorities said.

Skyguide, the air navigation service, initially said the closure would be in effect “until further notice” after the malfunction early in the morning.

A few hours later, it said the airspace closure was lifted at 8:30 a.m. (0630 GMT; 2:30 a.m. EDT) and air traffic over Switzerland was resuming along with operations at the country’s two national airports in Geneva and Zurich.

“Skyguide regrets this incident and its consequences for its customers and partners, as well as for the passengers at the two national airports,” it said in a statement.

Skyguide said the problem - a network malfunction at a Geneva computer centre - was identified at 4am on Wednesday. A cyber attack has definitely been ruled out as a possible cause, said Skyguide.

At no time was the safety of passengers threatened, Alex Bristol, director of Skyguide, told Swiss public radio, RTS.
