A defective CrowdStrike Falcon content update (a Channel File matching C-00000291*.sys) caused Windows hosts globally to blue-screen or enter boot loops, disrupting airports, hospitals, emergency services, broadcasters and large corporate fleets; CrowdStrike reverted the problematic content, published workarounds (delete the channel file or roll back snapshots / detach and fix VM volumes) and advised customers to use official support channels.
