Crowdstrike Outages

The CrowdStrike outages in July 2024 were caused by a faulty software update to their security software. This update led to widespread crashes of Microsoft Windows systems, affecting approximately 8.5 million devices globally. The incident disrupted critical services across industries like airlines, banks, hospitals, and government operations. Financial damages were estimated at over $10 billion.

CrowdStrike quickly identified the issue and released a fix, but many systems required manual intervention, prolonging the recovery process.
