According to CNBC, Microsoft’s cloud services have been restored, but some users still reported issues. The outage is linked to problems with a recent update from Austin-based cybersecurity firm CrowdStrike, which affected Windows systems globally, causing the infamous “blue screen of death.”
CrowdStrike CEO George Kurtz clarified on Friday morning that the issue, which did not affect Mac or Linux computers, was not related to a security incident or cyberattack. The defect in the update has been identified and isolated, with a fix deployed.
