World News Microsoft says 8.5m of its devices affected by outage Blog

A global technical outage related to a software update from cybersecurity company CrowdStrike affected nearly 8.5 million Microsoft devices, according to the technology company.

“We currently estimate that the CrowdStrike update affected 8.5 million Windows devices, or less than one percent of all Windows machines,” Microsoft said in the blog.

A software update from global cybersecurity firm CrowdStrike, one of the industry's largest operators, triggered system problems that grounded flights, forced broadcasting stations to suspend transmissions and left customers without access to services such as healthcare or banking.

“Although the percentage was small, the broad economic and societal impact reflects the use of CrowdStrike by organizations that operate many critical services,” Microsoft said in its blog post.

CrowdStrike helped develop a solution to help speed remediation of Microsoft's Azure infrastructure, Microsoft said. The company is currently working with Amazon Web Services and Google Cloud Platform and sharing information about the impacts Microsoft is seeing across the industry.

The aviation industry was recovering on Saturday from the outage that led to the cancellation of thousands of flights, leaving passengers either stranded or facing hours-long delays as airports and airlines were affected by the IT outage.

Delta Air Lines, one of the hardest-hit airlines, said on Saturday that more than 600 flights had been canceled, adding that more cancellations were expected.
