The CrowdStrike outage had a significant impact on government services. Among those impacted and reported were the Social Security Administration offices who had to close for the day due to the incident. Additionally, the Federal Communications Commission reported that some 911 services were disrupted, including state and local governments. The Cybersecurity and Infrastructure Security Agency (CISA) is working with CrowdStrike, Microsoft, and their federal, state, local, and critical infrastructure partners to fully assess and address system outages.
The global outage caused significant disruptions to various sectors including airlines, airports, banks, hotels, hospitals, manufacturing, stock markets, broadcasting, gas stations, retail stores, and more. The estimated financial impact worldwide is believed to exceed US$10 billion. Although a solution was promptly provided, the recovery efforts are still in progress as affected systems require manual intervention, along with addressing the resulting issues.
