Microsoft reports widespread disruption to 8.5 million Windows devices due to CrowdStrike update issue

A global IT outage occurred due to a corrupted software update from CrowdStrike, affecting nearly 8.5 million Microsoft devices worldwide, according to Microsoft. This estimate suggests it could be the worst cyber event in history. The glitch caused widespread disruptions, including grounding flights, forcing broadcasters off air, and leaving customers without access to healthcare or banking services. While Microsoft estimates that less than one percent of all Windows machines were affected, this still translates to a significant number of devices impacted globally. The outage's biggest continuing effect has been on air travel, with thousands of flights canceled on Friday.
