The Microsoft outage, linked to CrowdStrike’s Falcon Sensor, led to 'Blue Screen of Death' errors and widespread service disruptions in various industries, including hospitals, banks, airlines, emergency services, and supermarkets. In the recent incident, an update to CrowdStrike's Falcon product caused significant disruptions globally.
