CrowdStrike outage: What went wrong and why the fix is more challenging
Technical error caused global disruption
A faulty software update issued by security giant CrowdStrike has resulted in a massive overnight outage that's affected Windows computers.
The company CrowdStrike, based in Austin, Texas, makes software used by multinational corporations, government agencies, and countless individuals.
CrowdStrike CEO George Kurtz released a statement on Friday evening saying the outage was caused by a defect in a content update for its Falcon endpoint detection and response (EDR) product.
Slow recovery efforts
The outage began around 10 p.m. ET on Thursday and affected millions of devices worldwide. CrowdStrike initially said it had resolved the issue by 5 a.m. ET on Friday, but many users continued to experience problems throughout the day.
Kurtz said in a statement that the company is working "around the clock" to resolve the issue, but he warned that it may take some time.
Why the fix is challenging
The CrowdStrike outage is more difficult to fix than a typical software problem because it affects the way that Windows computers communicate with each other.
When a Windows computer starts up, it looks for a file called "boot.ini." This file contains the instructions that tell the computer how to load the operating system. In the case of the CrowdStrike outage, the faulty software update corrupted the boot.ini file on millions of computers.
This corruption made it impossible for the computers to load the operating system, resulting in the widespread outage.
Conclusion
The CrowdStrike outage is a reminder of how important it is to keep software up to date. When a software update is released, it's important to install it as soon as possible to avoid potential problems.
