A significant global technology outage on July 19, triggered by a faulty update from cybersecurity firm CrowdStrike, affected various sectors including healthcare, air travel, and broadcasting. Glengarry Memorial Hospital in Ontario had to shut down its laboratory for most of the day due to the disruption, which lasted until July 22. The outage also led to the cancellation and delay of thousands of flights worldwide, stranding passengers and complicating airline operations. Despite initial fears, CrowdStrike clarified that the incident was not a cyberattack but rather a software issue with computers running Microsoft Windows. Recovery efforts are ongoing, particularly in Britain's transport system, where disruptions coincided with the start of summer holidays for many students. Experts believe that while the worst may be over, it will take time for all affected services to fully normalize.
