AP-NORTHEAST-1 リージョンにおける API エラー率の上昇および起動失敗について、回復の兆候が見られております。EC2 および EBS の CloudWatch ヘルスデータは、現在正常に報告されております。引き続き復旧作業の進捗を監視し、次回の更新は日本時間午前 3 時までに、もしくは新たな情報が入り次第、お知らせいたします。 | We are seeing early signs of recovery for the elevated API error rates and launch failures in the AP-NORTHEAST-1 Region. EC2 and EBS CloudWatch health data is now reporting correctly. We will continue to monitor the progress of our recovery efforts and will provide you with another update by 10:00 AM PST or sooner as new information becomes available.

現在 AP-NORTHEAST-1 リージョンにおいて、API エラー率の上昇および起動失敗が発生しております。起動失敗は引き続き単一のアベイラビリティーゾーン (apne1-az1) に集中しているように見受けられますが、他のアベイラビリティーゾーンにおいても少数の起動失敗が発生しております。 影響を受けているアベイラビリティーゾーンでは、EC2 および EBS リソースの CloudWatch アラームが Insufficient Data 状態に移行しており、Insufficient Data でアラートを発生するよう設定されているアラームは、アラーム状態に移行する可能性があります。影響を受けているアベイラビリティーゾーンにおける DescribeInstanceStatus API は、Insufficient Data を返しております。稼働中のインスタンスに影響はございませんが、インスタンスの正常性は、お客様ご自身のヘルステレメトリーに基づいてご判断くださいますようお願いいたします。 さらに、ECS および Fargate のタスク起動失敗、ELB のプロビジョニング遅延、NAT Gateway の作成および関連付け解除のワークフローの失敗など、他サービスにも影響が発生しております。 根本原因は特定済みであり、現在問題の軽減に取り組んでおります。次回の更新は、日本時間午前 2 時 45 分までに、もしくは新たな情報が入り次第、お知らせいたします。 | We are experiencing elevated API error rates and launch failures in the AP-NORTHEAST-1 Region.

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 alarms 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 ano
