An IT failure caused by a software update from cybersecurity company CrowdStrike wreaked havoc worldwide on Friday, resulting in canceled flights, disrupted healthcare services, and halted business operations. Experts warned that full recovery from the “largest outage in history” could take weeks, as affected PCs may need to be fixed manually. The incident highlighted concerns about the lack of contingency plans in organizations when IT systems fail.
Ministers in the UK were coordinating responses through the Cobra committee, working with industries impacted by the outage. CrowdStrike’s founder apologized for the incident, attributing it to a software update error that affected Microsoft’s Windows operating system. The outage had ripple effects globally, impacting automotive supply chains, digital services in Kenya and Ukraine, payment systems in Australia, and various financial services and media outlets.
In the UK, services such as Visa, supermarkets, banks, transportation, and media outlets experienced disruptions. Leading cybersecurity consultant Troy Hunt described the event as the largest IT outage in history, likening it to the Y2K concerns that had worried experts in the past. Organizations in various sectors struggled to address the issue, with some facing manual reboots of affected machines, potentially taking weeks to resolve.
The aviation industry was severely impacted, with airports and airlines around the world reporting technical issues and cancellations. Heathrow Airport and major US carriers were affected, leading to flight disruptions. Healthcare services, including hospitals, pharmacies, and GP practices, also faced challenges accessing patient records and booking appointments. Despite the widespread impact, it was noted that 999 emergency services were unaffected by the IT failure.
Experts stressed the need for improved contingency plans and network resilience to prevent future similar incidents from causing such widespread disruptions. While the recovery effort was underway, it was anticipated that services would gradually resume, but the incident highlighted vulnerabilities in many organizations’ IT systems.
