A global IT outage caused by a faulty software update from cybersecurity firm CrowdStrike has led to widespread disruption affecting airlines, banks, hospitals, and other services since Friday. The outage, which impacted Microsoft Windows systems, has parallels to a similar incident in 2010 involving CEO George Kurtz when he was CTO at McAfee. Despite CrowdStrike's rapid deployment of a fix, many organizations are still dealing with the cascading effects, which could take days or even weeks to fully resolve. Key services like air travel, healthcare, and finance have been particularly hard-hit, highlighting the vulnerabilities in the world’s interconnected tech infrastructure. The incident has raised significant concerns about the reliance on a few major cybersecurity providers and the need for better contingency planning.
