November 27, 2025 — A massive outage affecting several global cloud providers temporarily disrupted banking, logistics, and news services across North America, Europe, and Asia. While systems are mostly restored, governments have launched joint investigations into what experts call “the most synchronized disruption since 2021.”
What happened
The outage, first detected early Thursday UTC, brought down sections of financial networks, airline check-in systems, and smaller media websites. Analysts say the failure originated from a compromised content delivery network node affecting multiple cloud ecosystems simultaneously.
India’s Computer Emergency Response Team (CERT-In), the European Union Agency for Cybersecurity (ENISA), and the U.S. Cybersecurity and Infrastructure Security Agency (CISA) are coordinating responses. No group has claimed responsibility, but preliminary forensics point to a “coordinated vulnerability exploit” in shared infrastructure software.
Governments on alert
Officials in Washington, Brussels, and New Delhi have called emergency briefings with major cloud providers. A European Commission spokesperson described the event as a “wake-up call for digital sovereignty,” while the U.S. Department of Homeland Security confirmed a “cross-sector review” is underway.
Cybersecurity experts say this may accelerate international standards for shared cloud infrastructure. “The outage shows the need for better segmentation and transparency among hyperscale providers,” noted analyst Priya Sharma of GlobalTech Watch.
Industry reaction
Cloud providers have not publicly disclosed the root cause, but early indicators suggest a vulnerability in network authentication protocols. Multiple firms are testing emergency failovers and redundancy layers to prevent recurrence.
Shares of leading providers dipped briefly on global exchanges before recovering by midday. Cyber-insurers report a temporary spike in inquiries from enterprise clients seeking downtime coverage.
What’s next
Investigations may take weeks, but the incident has already reignited calls for a global cybersecurity framework. A United Nations working group on digital stability is expected to issue new recommendations by year-end.
