CrowdStrike Update Triggers Widespread BSOD Issues: Thousands of Windows machines are currently experiencing severe disruptions due to a Blue Screen of Death (BSOD) issue at boot, impacting diverse sectors including banks, airlines, TV broadcasters, and supermarkets. The root cause of this widespread outage is attributed to a faulty update from the cybersecurity provider CrowdStrike, which has left affected PCs and servers inoperable, initiating a recovery boot loop that prevents proper startup.
The Global Impact of the BSOD Issue
The repercussions of this BSOD issue are extensive, affecting a multitude of businesses worldwide. Initial reports surfaced from Australian banks, airlines, and TV broadcasters, who were the first to encounter the problem. As the business day progressed in Europe, similar issues began to emerge, causing significant disruptions.
Key Incidents and Affected Entities

Technical Details and Root Cause
The issue stems from a faulty update to the kernel level driver used by CrowdStrike to secure Windows machines. This update has inadvertently caused widespread BSODs, rendering affected systems unable to boot properly.
CrowdStrike’s Response and Challenges
CrowdStrike CEO George Kurtz has stated that the issue has been identified and a fix has been deployed. However, restoring functionality to the impacted machines presents significant challenges for IT administrators. The faulty update has already caused substantial damage, and remediation efforts involve complex steps such as booting into safe mode and manually deleting a system file from the CrowdStrike directory.
IT Administrators’ Struggle
In numerous online forums, IT administrators are expressing their frustrations and sharing experiences:
- Reddit Threads: Hundreds of IT admins are reporting issues and sharing workaround steps. One poster mentioned that their entire company is offline, while another highlighted that 70 percent of their laptops are down and stuck in a boot loop.
- Cloud-based Servers and Remote Laptops: These systems pose additional difficulties, as the workaround steps are more complicated to execute on cloud infrastructure and remotely deployed laptops.
Separate Outage: Microsoft 365 Apps and Services
In a related but separate incident, Microsoft is dealing with recovery from several issues affecting its Microsoft 365 apps and services. The root cause was traced back to a configuration change in a portion of Azure backend workloads, further complicating the day’s challenges for IT professionals worldwide.
Conclusion
The BSOD issue caused by a faulty CrowdStrike update has resulted in a global disruption, affecting multiple sectors and causing significant operational challenges. As CrowdStrike works to resolve the issue, IT administrators worldwide face a daunting task of restoring functionality to affected systems. This incident underscores the critical importance of reliable cybersecurity updates and the far-reaching impact of technical issues in our interconnected world.
