On 19 July 2024, a faulty update to security software produced by CrowdStrike, an American cybersecurity company, caused many computers and virtual machines running Microsoft Windows to crash, affecting a wide range of users, including airlines, airports, banks, hospitals, stock markets, and broadcasting services. The error was discovered and a fix was identified on the same day, but the outage continues to delay airline flights, cause problems in processing electronic payments, and disrupt emergency services. The incident has been characterised as the "largest IT outage in history".

At the time of the incident, CrowdStrike said it had more than 24,000 customers[32], including nearly 60% of Fortune 500 companies and more than half of the Fortune 1,000.[33][34] The number of individual computers affected is hard to pinpoint.[35]

Definitely hard to determine a real number. 24,000 customers with 100 clients each? Some with several thousand each? Several million servers across some of the largest and most ubiquitous companies in America.

Long ago when I worked in enterprise IT management, the largest customers had ~500k endpoints under management, something like 90% Windows.
