Global IT Outage Disrupts Airports Worldwide
On July 19, 2024, a massive IT outage caused by Microsoft and CrowdStrike unleashed chaos in airports globally, resulting in extensive flight delays and cancellations. The malfunction led to the infamous "blue screen of death" dominating flight update and check-in screens across various airports, impacting individual travelers and major establishments such as financial institutions and air travel hubs during the peak holiday season.
By 2 p.m. ET, a staggering 34,000 flights had encountered global delays, while over 3,800 flights faced cancellations. Efforts from the U.S. Federal Aviation Administration (FAA) and airlines worked tirelessly to restore regular operations, yet intermittent ground stops and delays persisted. U.S. Secretary of Transportation Pete Buttigieg foresaw a return to normalcy by Saturday, recognizing the disruptive ripple effect of the outage.
Prominent carriers like American Airlines, Delta, and United grappled with disruptions, some recommencing flights while bracing for ongoing delays and cancellations. Travel waivers were issued to accommodate affected passengers. European airlines such as KLM and Air France also encountered substantial disruptions, with operations gradually returning to normal but with the looming potential for delays.
The impact of the outage struck particularly hard at bustling airports like those in Amsterdam, Berlin, and Zurich. Notably, airlines in mainland China remained unaffected due to their usage of different systems. This episode underscored the vulnerability of global IT infrastructure and the extensive repercussions of such widespread outages.
