A global Microsoft software outage on July 19, caused by a faulty update from cybersecurity firm CrowdStrike, disrupted multiple sectors worldwide. The update, which led to a 'Blue Screen of Death' on millions of Windows computers, halted operations for airlines, banks, emergency services, and media outlets. Thousands of flights were canceled, and 911 services in the U.S. were affected. Scammers exploited the situation, prompting warnings from authorities about phishing attempts. While some sectors like Indian stock exchanges remained unaffected, significant disruptions were reported in airports and corporate operations globally.
