Network Connectivity Issues

5:00 PM PDT We are investigating connectivity issues for some EC2 instances, RDS databases and degraded performance for some EBS volumes in a single Availability Zone (APNE2-AZ2) in the AP-NORTHEAST-2 Region. We are working to resolve the issue. If you have any questions or are experiencing any operational issue with any of our services, please contact the AWS Support department via the AWS Support Center at https://console.aws.amazon.com/support.

5:11 PM PDT Starting at 4:29 PM PDT, we experienced a loss of power to the underlying hardware for some EC2 instances and EBS volumes within a single Availability Zone in the AP-NORTHEAST-1 Region. Power was restored at 4:36 PM PDT, and the affected EC2 instances and EBS volumes began to recover. At this stage, the majority of affected EC2 instances and EBS volumes have recovered, and we continue to work on the small number that are still affected. Some RDS databases also experienced connectivity issues during this time period. Multi-AZ databases successfully failed away from the affected Availability Zone, but single-AZ databases would remain impaired until the power was restored. Other Availability Zones are not affected by this issue. If you have any questions or are experiencing any operational issue with any of our services, please contact the AWS Support department via the AWS Support Center at https://console.aws.amazon.com/support.

5:31 PM PDT We can confirm that power has been restored to the underlying hardware of all affected EC2 instances and EBS volumes. EC2 instances and EBS volumes continue to recover and we now have a small number of instances – mostly i3 instances – and degraded performance for a small number of EBS volumes in the affected Availability Zone. Single-AZ RDS databases – including RDS Aurora – experienced impact in the affected Availability Zone, but are recovering as power is restored. All multi-AZ RDS databases have failed away from the affected Availability Zone. A small number of single-AZ Application Load Balancers experienced elevated packet loss within the affected Availability Zone, but other load balancing traffic was shifted to other Availability Zones. API Gateway experienced elevated packet loss for M-TLS requests within the affected Availability Zone, but has now fully recovered. We continue to work on the small number of EC2 instances and EBS volumes that are still affected.
