A global IT outage, triggered by an update from cybersecurity firm CrowdStrike, caused widespread disruptions across multiple sectors, including aviation, finance, and healthcare. The outage primarily impacted Microsoft's Windows systems, resulting in delayed and canceled flights worldwide, with airports switching to manual operations. Major airlines like Delta, United, American, IndiGo, and SpiceJet experienced significant delays and cancellations. The issue began around 10:30 am on Friday and was nearly resolved by Saturday morning, with most systems back online. Hospitals worldwide faced technical issues, with some postponing procedures. CrowdStrike's CEO apologized for the software bug that caused the issue, emphasizing the rapid identification and remediation of the problem.
