A global technology outage caused by a glitch in CrowdStrike security software led to history's biggest IT meltdown, affecting airports, hospitals, and borders worldwide, with estimated damages of $24 billion. The outage, which affected Microsoft Windows systems, resulted in long queues at border crossings, delays in operations at hospitals in Germany, and chaos in various sectors globally. U.S. Customs and Border Protection faced processing delays, leading to hours-long waits at border crossings, significantly impacting international travel and trade. The outage, linked to a software update by CrowdStrike, also grounded flights, disrupted services, and left individuals unable to access essential services.
