Between 3:58 AM and 4:40 AM PDT, we experienced increased error rates and increased launch failures for EC2 instances in a single Availability Zone (euw3-az2) in the EU-WEST-3 Region. During this time, customers attempting to launch new EC2 instances in the affected Availability Zone would have experienced launch failures. Additionally, a subset of existing EC2 instances and EBS volumes in this Availability Zone were impacted and became unreachable. We have identified the root cause to be a loss of power to infrastructure within the affected Availability Zone. Engineers were engaged at 4:02 AM and immediately began working to restore power and assess the scope of impact. By 4:20 AM, power was successfully restored to the affected infrastructure. We then focused our efforts on recovering impacted EC2 instances and EBS volumes. By 4:40 AM, all impacted EC2 instances and EBS volumes had been fully recovered and were operating normally. No additional action is required for EC2 instances and EBS volumes that were impacted during the power loss event, as these have been fully recovered. While EC2 and EBS have recovered, some AWS services may take additional time to fully recover as they process backlogs and complete their own recovery procedures. The issue has been resolved and the service is operating normally.

We are investigating instance connectivity issues in a single Availability Zone (euw3-az2) in the EU-WEST-3 Region.

We are providing an update on the ongoing service disruptions affecting the AWS Middle East (Bahrain) Region (ME-SOUTH-1). We continue to make progress on recovery efforts across multiple workstreams. With the immediate phase of this event now better understood, we are moving to a more targeted communication model. Going forward, updates will be delivered directly to affected customers through the AWS Personal Health Dashboard. Customers who require assistance with this event are encouraged to contact AWS Support through the AWS Management Console or the AWS Support Center. We continue to strongly recommend that customers with workloads running in the Middle East take action now to migrate those workloads to alternate AWS Regions. Customers should enact their disaster recovery plans, recover from remote backups stored in other Regions, and update their applications to direct traffic away from the affected Regions. For customers requiring guidance on alternate regions, we recommend considering AWS Regions in the United States, Europe, or Asia Pacific, as appropriate for your latency and data residency requirements.

We are providing an update on the ongoing service disruptions affecting the AWS Middle East (UAE) Region (ME-CENTRAL-1). We continue to make progress on recovery efforts across multiple workstreams. For Amazon S3, we are seeing continued improvement in PUT and LIST availability. Newly written objects are now able to be successfully retrieved, and we continue to work on reducing GET error rates for objects written prior to the event. Full recovery of GET operations for pre-existing data remains dependent on restoring the affected infrastructure. For Amazon DynamoDB, error rates remain elevated and our teams continue to focus on recovery; we expect to see improvement over the coming hours. As these foundational services recover, dependent services — including AWS Lambda, Amazon Kinesis, Amazon CloudWatch, and Amazon RDS — will follow. Amazon EC2 instance launches remain throttled in the ME-CENTRAL-1 Region and will be relaxed as foundational service recovery and capacity allow. The AWS Management Console is operational, though customers may continue to experience errors on certain pages as underlying services work through their recovery.

Recovery efforts in the affected Availability Zone (mes1-az2) in the ME-SOUTH-1 Region are ongoing, with the situation remaining consistent with our last update. We have no change to expected timelines for fully restoring power and connectivity. While progress is being made, significant work remains before full restoration is complete. We continue to recommend customers launch replacement resources in one of the unaffected Availability Zones or an alternate AWS Region. Given the extended nature of this event, we continue to encourage customers to replicate Amazon S3 data and other critical workloads from ME-SOUTH-1 to another AWS Region using the guidance shared previously. We will provide our next update by 12:00 PM PST on March 3, or sooner if conditions change.
