IT breakdown Skyguide lifts traffic reduction after global IT outage

Global IT failures had an impact on air traffic on Friday morning. Skyguide air traffic control temporarily reduced capacity for transit traffic and approaches to Zurich by 30 percent. The measure was lifted in the afternoon.

Skyguide was also affected by the global disruption caused by a failed update to a program from the IT security company Crowdstrike, as reported by the air traffic control authority. The problem partially affected corporate IT.

In the afternoon, the company wrote that the restrictions on transit traffic had been lifted with immediate effect. Skyguide is also working normally again for arrivals and departures. Safety in Swiss airspace was guaranteed at all times, it added.
