A recent update from CrowdStrike is causing computers running Windows to crash and display the Blue Screen of Death, affecting companies worldwide. Sky News, among others, has reported being unable to broadcast due to this issue.

Users have expressed their frustration on forums like Reddit. One user described the situation: “Wow, stuck in a boot loop, and entire org taken out.”

The problem stems from an issue with CrowdStrike’s Falcon Sensor product, designed to prevent breaches using cloud-delivered technologies. This IT outage has impacted airports, businesses, and broadcasters globally, grounding planes in the U.S. and affecting trains in the U.K.

Microsoft is taking mitigation actions after service issues started around 6pm Eastern Time, affecting several apps and services.

CrowdStrike engineers are working on resolving the issue, which is linked to a faulty channel file rather than a direct update. Both CrowdStrike and Microsoft have been contacted for comments, and updates will follow once they respond.

If you’re experiencing these issues, know you’re not alone and steps are being taken to address the problem.
