**2. Added: Update** (update) · 2026-11-11 16:40 UTC

```diff
+ We are experiencing elevated API error rates and launch failures in the AP-NORTHEAST-1 Region. While launch failures still appear to be concentrated in a single Availability Zone (apne1-az1), we are now seeing low levels of launch failures in other availability zones as well. Cloudwatch metrics for EC2 and EBS resources in the affected Availability Zone are transitioning into Insufficient Data state and alarms configured to alert off of Insufficient Data may transition to Alert state. The DescribeInstanceStatus API in the affected Availability Zone is returning Insufficient Data. Running instances are not affected, and you should rely on your own health telemetry to determine the health of your instance. In addition, we are seeing impact to other services such as ECS and Fargate Task Launch failures, ELB provisioning delays and Nat Gateway failures for Create and Disassociate workflows. We have identified the root cause and are working to mitigate the issue. We will provide you with another update by 9:45 AM PST or sooner as new information becomes available.
