A routine software update from cybersecurity firm CrowdStrike caused major disruptions for companies worldwide, including airlines, hospitals, banks, and courthouses. The update, which was intended to be uneventful, ended up grounding operations for many large corporate and government agencies.
CrowdStrike stated that the issue was not a cyberattack and that a fix had been deployed. However, the incident led to widespread outages affecting customers using a version of the Windows operating system.
Following the CrowdStrike outage, Microsoft’s cloud platform Azure also experienced issues, although Microsoft confirmed that the two incidents were unrelated. The impact of the CrowdStrike update was felt by various industries, with airlines like American Airlines, Delta, and United issuing ground stops, hospitals canceling surgeries, and 911 emergency lines going down in some states.
Downdetector detected user issues at numerous U.S. companies, although some like BW were not directly affected by the outage.
As of 1 p.m. ET, Downdetector continued to report potential user issues at banks and financial services, telecommunications, cable, wireless companies, and other consumer services.
