In an update on its investigation into the crisis, which is still being felt, CrowdStrike said a code fault had slipped past its own safety procedures, forcing computers running Microsoft’s Windows operating system to crash.
The cause of Friday’s outage, which knocked out systems across the world disrupting everything from flights to health appointments, focused on the company’s Falcon Sensor.
