On October 20, 2025, Amazon Web Services (AWS) experienced a significant outage originating in its US-EAST-1 region, leading to widespread disruptions across the internet. The incident, which began around 11:49 PM PDT on October 19, was traced to a Domain Name System (DNS) resolution failure affecting DynamoDB API endpoints. This failure cascaded, impairing multiple AWS services and the numerous applications that rely on them. AWS reported that the issue was fully mitigated by 2:24 AM PDT on October 20, with all services returning to normal operations by 3:01 PM PDT.
