Microsoft outage: What is CrowdStrike, the service causing ‘Blue Screen of Death’ worldwide

Microsoft Windows users around the world including India, Australia, Germany, United States, United Kingdom and others are seeing blue screen issue on their laptops. This caused their systems to automatically reboot or shut down. Companies like Dell Technologies said this crash was caused by a recent CrowdStrike update.

The outage, which began Thursday night and affected Microsoft’s Central America region, crippled the core systems of many airlines, including American Airlines, Frontier Airlines, Allegiant and Sun Country in the US, as well as IndiGo and other airlines in India.

It was not immediately clear if all of the reported outages were related to Crowdstrike issues or if other issues were at play.

What is CrowdStrike?

CrowdSrike is a cybersecurity platform that provides security solutions to users and businesses. Falcon Identity Threat Protection stops identity breaches managed in real-time using a single sensor and unified threat interface with attack correlation across endpoints, workloads and identities.

The buggy update was reported to be caused by CrowdStrike’s Falcon Sensor not working properly and conflicting with Windows.
