Financial Services
Banks and financial institutions experienced significant disruptions, with traders facing issues executing transactions. The London Stock Exchange’s news and data platform, along with other critical services, affected but restored by midday.
Healthcare
U.S. healthcare providers reported that call centers, patient portals, and other operations were impacted. Major hospitals like Mass General Brigham and Tufts Medical Center had to limit services and warned of delays.
Government Services
Government agencies worldwide faced issues, with the Dutch and UAE foreign ministries reporting disruptions. In New York City, essential functions like jail cameras and arrest processing software affected, though emergency systems remained operational.
Media and Entertainment
Broadcasting services like Sky News went off air, and sports organizations like Manchester United had to postpone ticket releases. The outage revealed the dependency of media on digital systems.
Response and Recovery
CrowdStrike’s CEO, George Kurtz, publicly apologized and stated that systems were gradually coming back online as users rebooted their systems. While CrowdStrike shares fell by 10.8%, its rivals like SentinelOne and Palo Alto Networks saw gains. Microsoft supported its customers in recovering their systems post-update.
