The CrowdStrike update triggered a global outage resulting in Microsoft Windows machines experiencing blue screen (BSOD) errors and getting stuck in a recovery loop. The error caused widespread disruption for Windows users, businesses, and even airports.
- The primary cause was identified as the latest update to the CrowdStrike agent Falcon Sensor.
- Windows hosts running this software were particularly affected.
- The Blue Screen of Death (BSOD), also known as a stop error, is a protective measure by the Windows operating system.
- When a BSOD occurs, the computer halts all operations, preventing damage to the system and data corruption. This error screen is characterised by a blue background with white text, including an error code and a brief description of the problem.
- The BSOD provides information about the error that caused the crash, allowing users and IT professionals to diagnose and resolve the issue.
