A widespread IT outage, caused by a defective software update from cybersecurity firm CrowdStrike, is affecting businesses worldwide, causing significant disruptions across various sectors. The issue has primarily impacted computers running Windows, resulting in system crashes and “blue screen of death” errors. The travel industry appears to be among the hardest hit, with airlines and airports in multiple countries reporting problems with check-in and ticketing systems, leading to flight delays. Other affected sectors include banking, retail, and healthcare.
CrowdStrike CEO George Kurtz confirmed the outage was due to a “defect” in a content update for Windows hosts, ruling out a cyberattack. The company is working on a fix. CrowdStrike said the crash reports were “related to the Falcon Sensor” — its cloud-based security service that it describes as “real-time threat detection, simplified management, and proactive threat hunting.”
A Microsoft spokesperson told TechCrunch that the previous Microsoft 365 service disruption overnight July 18-19 was unrelated to the widespread outage triggered by the CrowdStrike update.
