The Microsoft blackout refers to the widespread global IT disruptions triggered by a faulty software update from cybersecurity firm CrowdStrike, which crippled Windows-based systems across critical sectors. The incident caused significant operational chaos, grounding flights, halting banking services, and impacting healthcare facilities and media outlets worldwide. While the scale of the outages led to initial concerns regarding a potential cyberattack, experts and officials have confirmed the event was the result of a technical configuration error rather than malicious activity.
