Between 11:49 PM PDT (Oct 19) and 3:01 PM PDT (Oct 20), AWS US-EAST-1 experienced elevated error rates and latency due to DNS issues affecting DynamoDB and dependent services (EC2, Lambda, CloudWatch, IAM, etc.). AWS mitigated DNS and EC2 subsystem impacts, restored Network Load Balancer health checks by 9:38 AM, and gradually reduced throttling until full recovery. All services are now operating normally.
