It was not immediately clear whether the call to keep flights from taking off were related to an earlier Microsoft (MSFT.O), opens new tab cloud outage.

In Australia, media, banks and telecoms companies suffered outages, which the government said appears to be linked to an issue at global cybersecurity firm Crowdstrike .

Crowdsourced website Downdetector showed outages at several banks and telecoms companies.

Crowdstrike ran a recorded phone message on Friday when Reuters contacted its technical support saying it was aware of reports of crashes on Microsoft's Windows operating system relating to its Falcon sensor, without mentioning Australia.

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.

AWS cloud service provider said in a statement that it was "investigating reports of connectivity issues to Windows EC2 instances and Workspaces within AWS."

It was not immediately clear whether all reported outages were linked to Crowdstrike problems or there were other issues at play.
