A global IT outage caused by a faulty software update from cybersecurity firm CrowdStrike disrupted numerous services worldwide, impacting airports, hospitals, government agencies, and businesses. Key affected areas included Los Angeles International Airport, New York State DMV, hospitals across Southern California, and Starbucks locations. The outage also led to delays in U.S. Customs and Border Protection processing, grounded flights across the country, and disrupted 911 services in multiple states. Hospitals faced delays in admissions and had to revert to manual record-keeping. Emergency services in several areas managed to maintain critical functions through backup systems and manual processes. Services began to recover by Friday, although some disruptions persisted into the weekend.
