One small update brought down millions of IT systems around the world. It’s a timely warning

This weekend’s global IT outage caused by a software update gone wrong highlights the interconnected and often fragile nature of modern IT infrastructure. It demonstrates how a single point of failure can have far-reaching consequences. The outage was linked to a single update automatically rolled out to Crowdstrike Falcon, a ubiquitous cyber security tool used primarily by large organisations. This caused Microsoft Windows computers around the world to crash.

CrowdStrike has since fixed the problem on their end. While many organisations have been able to resume work now, it will take some time for IT teams to fully repair all the affected systems – some of that work has to be done manually.
