Download Our Cyber Insights Document on the AWS Outage
In October 2025, Amazon Web Services (AWS) suffered a major outage in its US-EAST-1 region when a DNS race condition in its DynamoDB endpoint triggered cascading failures across more than 140 AWS services. The disruption affected thousands of organisations globally — halting e-commerce operations, freezing payment gateways, disrupting business communications, and even disabling smart-home systems for several hours.
The incident exposed a harsh reality: even the world’s most trusted cloud platforms can experience catastrophic downtime due to a single point of failure. As organisations move more of their critical workloads to the cloud, cyber resilience planning and incident response readiness become essential, not optional.
From delayed customer transactions to broken internal workflows, the AWS outage underscored the need for robust business continuity planning, multi-region redundancy, and well-rehearsed cyber incident response playbooks. The ability to communicate swiftly, coordinate recovery, and maintain stakeholder trust during such outages now defines operational maturity in a cloud-driven world.
Cyber Management Alliance helps organisations prepare for such events through:
- NCSC-Assured Cyber Incident Planning & Response Training
- Cyber Tabletop Exercises to simulate large-scale disruptions
- Incident Response Playbook Creation & Review Workshop
- Executive Cyber Awareness Briefings
When the next outage or cyber incident strikes, readiness determines resilience.
