New York: Major US airlines ground stops on Friday citing communications issues, while other carriers, media companies, banks and telecoms firms around the world also reported system outages were disrupting their operations.
Outages have been reported mainly in Australia, the US, the UK, and India, among other countries, affecting institutions ranging from banks, media houses, and stock markets to government branches and airports.
Microsoft said that its outage started at about 6pm Eastern Time on Thursday, with a subset of its customers experiencing issues with multiple Azure services in the Central US region.
Separately, Microsoft announced it was investigating an issue impacting various Microsoft 365 apps and services.
“We’re continuing to progress on our mitigation efforts for the affected Microsoft 365 apps and services,” Microsoft said on its website. “We still expect users to see remediation as we address residual impact.”
IT security firm Crowdstrike ran a recorded phone message on Friday saying it was aware of reports of crashes on Microsoft’s Windows operating system relating to its Falcon sensor.
American Airlines, Delta Airlines, United Airlines, and Allegiant Air grounded flights less than an hour after Microsoft said it resolved its cloud services outage that impacted several low-cost carriers.
It was not immediately clear whether the call to keep flights from taking off were related to an earlier Microsoft 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.
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.
