July 19 (Reuters) - Amsterdam's Schiphol Airport, one of

Europe's busiest hubs, is being affected by a global cyber

outage, a spokesperson said on Friday.

"The outage has an impact on flights flying from and to

Schiphol," he said, adding that it was not yet clear how many

flights were affected.

Belgian media said Brussels airport was affected as well.

"It concerns a malfunction of the Microsoft Azure system,

which many airlines use to check in baggage," Brussels Airport

told Belgian broadcaster VRT, adding it is now using an

alternative software program but that this might result in

slightly longer queues at check-in.

When contacted by Reuters U.S. software firm Crowdstrike in

a recorded phone message on Friday said it was aware of reports

of crashes of Microsoft's ( MSFT ) Windows operating system relating to

its Falcon sensor.

There was no information to suggest the outage was a cyber

security incident, the office of Australia's National Cyber

Security Coordinator Michelle McGuinness said in a post on X.
