We are investigating increased error rates when calling EC2 Launch Template APIs in US-EAST-1 Region. During this time, affected customers may experience errors when creating, modifying, or referencing launch templates. Other AWS services that rely on launch templates may also be impacted. We will provide another update by 6:30 AM PDT or sooner, if we have additional information to share.
resolved
Starting at 2:56 AM PDT, we began experiencing increased error rates when calling EC2 Launch Template APIs in the US-EAST-1 Region. Our engineers have been engaged and are actively working to mitigate the impact. Additionally, Amazon Elastic Kubernetes (EKS) customers may experience errors when creating or updating clusters, or when launching and scaling nodes via Managed Node Groups, EKS Auto Mode, or Karpenter; this issue does not impact existing clusters and nodes. We have identified the root cause to be a congestion issue within an EC2 internal subsystem responsible for processing EC2 launch template workflows. We are pursuing multiple mitigation paths. We recommend that customers retry any failed requests during the impact window. While we do not currently have an ETA for full recovery, we are prioritizing this issue and will provide another update by 7:15 AM PDT or sooner if we have additional information to share.

Between 2:56 AM and 6:54 AM PDT, we experienced increased error rates when calling EC2 Launch Template APIs in the US-EAST-1 Region. During this time, affected customers may have experienced errors when creating, modifying, or describing Launch Templates. Other AWS services that rely on Launch Templates were also impacted. Amazon EC2 instances and Amazon EKS workloads already running on provisioned nodes continued to operate normally. Cluster modification operations, and Managed Node Group creation were also impacted. For EKS Auto Mode, impact was limited to operations requiring new capacity or changes, including node provisioning and pod scheduling. Our engineers were automatically engaged and immediately began investigating the root cause. We identified the root cause as a congestion issue within an EC2 internal subsystem responsible for processing EC2 launch template workflows. At 3:26 AM PDT, we took mitigation actions by introducing throttling for the affected APIs and we saw some recovery which was communicated directly with a subset of customers via the 'Your Account view' of the AWS Health Dashboard. We took multiple additional mitigation paths, incrementally lifting these throttle limits, and by 6:54 AM PDT, the issue was fully mitigated. We recommend that customers retry any failed requests. The issue has been resolved and all AWS services are now operating normally.

resolved
We continue to investigate instance impairments to a single Availability Zone (use1-az4) in the US-EAST-1 Region. We have experienced an increase in temperatures within a single data center, which in some cases has caused impairments for instances in the Availability Zone. EC2 instances and EBS volumes hosted on impacted hardware are affected by the loss of power during the thermal event. Other AWS services that depend on the affected EC2 instances and EBS volumes in this Availability Zone, may also experience impairments. We will continue to provide updates as recovery continues.

We continue to work towards mitigating the increased temperatures to its normal levels in the affected Availability Zone (use1-az4) in the US-EAST-1 Region. Other AWS services that depend on the affected EC2 instances and EBS volumes in this Availability Zone, may also experience impairments. We have weighed away traffic for most services at this time. We recommend customers utilize one of the other Availability Zones in the US-EAST-1 Region at this time, as existing instances in other AZ's remain unaffected by this issue. Customers may experience longer than usual provisioning times. We will provide an update by 7:45 PM PDT, or sooner if we have additional information to share.
resolved
We are actively working to restore temperatures to normal levels in the affected Availability Zone (use1-az4) in the US-EAST-1 Region, though progress is slower than originally anticipated. Since our last update we have made incremental progress to restore cooling systems within the affected AZ, which will not be visible to external customers but are required for the restoration of affected services. In the impacted Availability Zone, EC2 Instances, EBS Volumes, and other AWS Services are also experiencing elevated error rates and latencies for some workflows. As part of our recovery effort, we have shifted traffic away from the impacted Availability Zone for most services. We recommend customers utilize one of the other Availability Zones in the US-EAST-1 Region, as existing instances in other AZs remain unaffected by this issue. If immediate recovery is required, we recommend customers restore from EBS Snapshots and/or replace affected resources by launching new replacement resources in one of the unaffected zones.

Mitigation efforts remain underway to resolve the impaired EC2 instances and degraded EBS volumes in a single Availability Zone (use1-az4) in the US-EAST-1 Region. These EC2 instances and EBS volumes were impacted due to a loss of power during the thermal event. The work to bring additional cooling system capacity online, which will enable us to recover the remaining affected infrastructure in a controlled and safe manner, is taking longer than we had initially anticipated. Some services, such as IoT Core, ELB, NAT Gateway, and Redshift, have seen significant improvements in the recovery of their workflows. However, some customers will continue to see their affected EC2 instances and EBS volumes as impaired until we achieve full recovery.

We continue to make progress towards resolving the impaired EC2 instances and degraded EBS volumes in a single Availability Zone (use1-az4) in the US-EAST-1 Region. At this time, we wanted to provide some more details on the issue. Beginning on May 7 at 4:20 PM PDT, we began experiencing an increase in instance impairments within the affected zone due to the loss of power during a thermal event. Engineers were automatically engaged within minutes and immediately began investigating multiple mitigations. By 9:12 PM PDT, we restored power to a subset of the affected infrastructure and observed some signs of recovery, which have remained stable.
We continue working to bring additional cooling system capacity online, which will enable us to recover the remaining affected hardware in the impacted zone in a controlled and safe manner. Some AWS services, such as IoT Core, ELB, NAT Gateway, and Redshift, continue to see significant improvements in the recovery of their workflows. However, some customers will continue to see their affected EC2 instances and EBS volumes as impaired until we achieve full recovery.

We continue our efforts to work towards the recovery of the impaired EC2 instances and degraded EBS volumes in a single Availability Zone (use1-az4) in the US-EAST-1 Region. We are making progress towards the restoration of the cooling system capacity that is required to recover the affected hardware in the impacted zone. Some customers will continue to see their affected EC2 instances and EBS volumes as impaired until the affected racks are recovered. We continue to recommend that customers who require immediate recovery restore from EBS snapshots and/or replace affected resources by launching new replacement resources in one of the unaffected zones.
As part of our parallel investigation, we have identified the root cause of the increased error rates and query failures for Redshift clusters in the US-EAST-1 Region. This has been confirmed to be related to impact from an upstream dependency. Affected customers may continue to see errors for resume and restart workflows, failover operations, and impact to general availability. We are actively working to resolve the issue.
Our timeline for full recovery is still expected to take several hours and will be incremental as we bring racks online in phases. We will provide an additional update by 12:30 PM or sooner if we have new information to provide.

We continue to work towards the recovery of the impaired EC2 instances and degraded EBS volumes in a single Availability Zone (use1-az4) in the US-EAST-1 Region though efforts are slower than we had previously anticipated. We are taking measured steps to ensure that cooling capacity is brought online in a safe and controlled manner. As a result, EBS Volumes and EC2 instances affected by the issue will continue to experience impairments. We continue to recommend that customers who require immediate recovery restore from EBS snapshots and/or replace affected resourced by launching new replacement resources.
Full recovery is still expected to take several hours. We will provide an additional update by 4:00 PM or sooner if we have new information to provide.

We have begun to see improvements in the overall number of affected EC2 instances and degraded EBS volumes in a single Availability Zone (use1-az4) in the US-EAST-1 Region. The steps taken to supply additional cooling capacity have been showing steady signs of progress. Some EBS Volumes and EC2 instances affected by the issue will continue to experience impairments while we continue to drive these efforts. We continue to recommend that customers who require immediate recovery restore from EBS snapshots and/or replace affected resources by launching new replacement resources.
In parallel, we have seen some improvements in Amazon Managed Streaming for Apache Kafka as a result of the parallel mitigation efforts being performed. We are still experiencing timeouts to partitions but are seeing continued progress.
We do anticipate that recovery will still take several hours. We will provide an additional update by 7:30 PM or sooner if we have new information to provide.
resolved
Starting May 7 4:20 PM PDT, we experienced increased impaired EC2 instances and degraded EBS volumes in a single facility (data center) within a single Availability Zone (use1-az4) in the US-EAST-1 Region. The issue was caused by a thermal event resulting in a loss of power. As part of our recovery effort, we shifted traffic away from the impacted Availability Zone for most services at May 7 5:06 PM.
AWS services, like Elastic Load Balancing, Elastic Kubernetes Service, ElastiCache, Redshift, OpenSearch, Managed Streaming for Apache Kafka among others, that depend on the affected EC2 instances and EBS volumes in this Availability Zone, also experienced elevated error rates and latencies for some workflows and/or configurations.
Our main effort during the event mitigation strategy was to bring back our cooling systems capacity. By May 8 1:50 PM, we were able to stabilize cooling system capacity to pre-event levels, which helped us to restore the majority of the impaired EC2 instances and EBS volumes. A small number of instances and EBS volumes remain impaired and we continue to work to recover all affected remaining resources.
We will communicate with customers who are still impacted via the Your Account view of the AWS Health Dashboard. Customers that require further assistance with this event may contact AWS Support through the AWS Management Console or the AWS Support Center.

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.

We are providing an update on the ongoing service disruptions affecting the AWS Middle East (UAE) Region (ME-CENTRAL-1) and the AWS Middle East (Bahrain) Region (ME-SOUTH-1). Due to the ongoing conflict in the Middle East, both affected regions have experienced physical impacts to infrastructure as a result of drone strikes. In the UAE, two of our facilities were directly struck, while in Bahrain, a drone strike in close proximity to one of our facilities caused physical impacts to our infrastructure. These strikes have caused structural damage, disrupted power delivery to our infrastructure, and in some cases required fire suppression activities that resulted in additional water damage. We are working closely with local authorities and prioritizing the safety of our personnel throughout our recovery efforts.
In the ME-CENTRAL-1 (UAE) Region, two of our three Availability Zones (mec1-az2 and mec1-az3) remain significantly impaired. The third Availability Zone (mec1-az1) continues to operate normally, though some services have experienced indirect impact due to dependencies on the affected zones. In the ME-SOUTH-1 (Bahrain) Region, one facility has been impacted. Across both regions, customers are experiencing elevated error rates and degraded availability for services including Amazon EC2, Amazon S3, Amazon DynamoDB, AWS Lambda, Amazon Kinesis, Amazon CloudWatch, Amazon RDS, and the AWS Management Console and CLI. We are working to restore full service availability as quickly as possible, though we expect recovery to be prolonged given the nature of the physical damage involved.
In parallel with efforts to restore the physical infrastructure at the affected sites, we are pursuing multiple software-based recovery paths that do not depend on the underlying facilities being fully brought back online. For Amazon S3 and Amazon DynamoDB, we are actively working to restore data access and service availability through software mitigations, including deploying updates to enable S3 to operate within the current infrastructure constraints and remediating impaired DynamoDB tables to restore read and write availability for dependent services. Our focus on restoring these foundational services is deliberate, as recovery of Amazon S3 and Amazon DynamoDB will in turn enable a broad range of dependent AWS services to recover. For other affected service APIs, we are deploying targeted software updates to reduce error rates and restore functionality where possible, independent of the physical recovery timeline. We are also working to restore access to the AWS Management Console and CLI through network-level changes that route traffic away from the affected infrastructure. While these software-based mitigations can address many of the service-level impacts, some recovery actions are constrained by the physical state of the affected facilities — meaning that full restoration of certain services will require the underlying infrastructure to be repaired and brought back online. Across all services, our teams are working in parallel on both the physical restoration of the affected facilities and these software-based mitigations, with the goal of restoring as much customer access as possible as quickly as possible, even ahead of full infrastructure recovery. In addition, we are prioritizing the restoration of services and tools that enable customers to back up and migrate their data and applications out of the affected regions.
Finally, even as we work to restore these facilities, the ongoing conflict in the region means that the broader operating environment in the Middle East remains unpredictable. We recommend that customers with workloads running in the Middle East consider taking action now to backup data and potentially migrate your workloads to alternate AWS Regions. We recommend customers exercise 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 will continue to provide updates as recovery progresses and as the situation evolves. Our next update will be provided by 9:00 PM PST on March 2, 2026, or sooner if new information becomes available.

We continue to work toward restoring power in the affected Availability Zone (mes1-az2) in the ME-SOUTH-1 Region. The overall state of the region remains largely unchanged from our previous update. At this time, we have no updated guidance on expected timelines for fully restoring power and connectivity. We are taking all necessary steps to support the recovery process. While progress is being made, significant work remains before full restoration is complete.
Given the ongoing uncertainty, we encourage customers to replicate their Amazon S3 data and other critical data from the ME-SOUTH-1 Region to another AWS Region, using the guidance provided in our previous update. We will continue to provide updates as recovery progresses and as the situation evolves. Our next update will be provided by 6:00 AM PST on March 3, or sooner if new information becomes available.

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.

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.
investigating
We are providing an update on the ongoing service disruption. The Middle East (Bahrain) Region (ME-SOUTH-1) has suffered damage due to the conflict in the Middle East and is currently unavailable. Customers should recover their resources in other Regions from remote backups. Relevant billing operations are currently suspended while we restore normal operations in this AWS Region. This process is expected to take several months.

We are investigating issues with AWS services in the ME-CENTRAL-1 Region.
resolved
We are investigating connectivity and power issues affecting APIs and instances in a single Availability Zone (mec1-az2) in the ME-CENTRAL-1 Region due to a localized power issue. Existing instances in this zone will also be affected. Other AWS Services may also be experiencing increased errors and latencies for their workflows, and we are working to route requests away from this affected Availability Zone. We recommend customers make use of other Availability Zones at this time. Targeting new launches using RunInstances in the remaining AZs should succeed. Existing instances in the other AZs are not affected.
resolved
We can confirm that a localized power issue has affected a single Availability Zone in the ME-CENTRAL-1 Region (mec1-az2). EC2 Instances, DB Instances, EBS Volumes, and others resources are currently unavailable and will experience connectivity issues at this time. Other AWS Services are also experiencing error rates and latencies for some workflows. We have weighed away traffic for most services at this time. We recommend customers utilize one of the other Availability Zones in the ME-CENTRAL-1 Region at this time, as existing instances in other AZ's remain unaffected by this issue. We are actively working to restore power and connectivity, at which time we will begin to work to recover affected resources. As of this time, we expect recovery is multiple hours away. We will provide an update by 7:15 AM PST, or sooner if we have additional information to share.
investigating
We wanted to provide some additional information on the isolated power issue. At this time, most AWS Services have weighted away from the affected Availability Zone (mec1-az2) and are seeing recovery for their affected operations and workflows. For EC2 Instances, EBS Volumes, and other resources that are impacted in the affected Zone, we will have a longer tail of recovery. At this time, power has not yet been restored to the affected AZ. For now, we recommend continuing to retry any failed API requests. If immediate recovery is required, we recommend customers restore from EBS Snapshots and/or replace affected resources by launching replacement resources in one of the unaffected zones, or an alternate region. As of this time, recovery is still several hours away. We will provide an update by 8:30 AM PST, or sooner if we have additional information to share.
investigating
We continue to work toward restoring power in the affected Availability Zone in the ME-CENTRAL-1 Region (mec1-az2). In parallel, we are actively working on improving error rates and latencies that some customers are observing for EC2 Networking and EC2 Describe APIs. Due to increased demand in the unaffected Availability Zones, customers may experience longer than usual provisioning times or may need to retry requests for certain instance types, or pick an alternative instance type. We will provide an update by 10:30 AM PST, or sooner if we have additional information to share.
investigating
We want to provide some additional information on the power issue in a single Availability Zone in the ME-CENTRAL-1 Region. At around 4:30 AM PST, one of our Availability Zones (mec1-az2) was impacted by objects that struck the data center, creating sparks and fire. The fire department shut off power to the facility and generators as they worked to put out the fire. We are still awaiting permission to turn the power back on, and once we have, we will ensure we restore power and connectivity safely. It will take several hours to restore connectivity to the impacted AZ. The other AZs in the region are functioning normally. Customers who were running their applications redundantly across the AZs are not impacted by this event. EC2 Instance launches will continue to be impaired in the impacted AZ. We recommend that customers continue to retry any failed API requests. If immediate recovery of an affected resource (EC2 Instance, EBS Volume, RDS DB Instance, etc.) is required, we recommend restoring from your most recent backup, by launching replacement resources in one of the unaffected zones, or an alternate AWS Region. We will provide an update by 12:30 PM PST, or sooner if we have additional information to share.
investigating
We are aware that some customers are experiencing errors when calling EC2 APIs, specifically networking related APIs (AllocateAddress, AssociateAddress, DescribeRouteTable, DescribeNetworkInterfaces). We are actively working on multiple paths to mitigate these issues. For customers experiencing throttling errors on the AllocateAddress APIs, we recommend retrying any failed API requests. We are deploying a configuration change to mitigate the AssociateAddress API errors and expect recovery in the next few hours. DescribeRouteTable and DescribeNetworkInterfaces API calls without specifying zone, Interface or Instance IDs are expected to fail until we restore the impacted zone. We recommend customers to pass these IDs explicitly in these API requests. For customers that can, we recommend considering using alternate AWS Regions. We will provide another update by 3:30 PM PST, or sooner if we have more to share.
investigating
We are seeing positive signs of recovery for many of the EC2 APIs, such as Describes and AllocateAddress. We recognize that customers are still experiencing errors when attempting to call the AssociateAddress API, and are unable to disassociate addresses from resources that are affected by the underlying power issue. We continue to work on multiple parallel paths to mitigate both of these issues. We recommend continuing to retry requests wherever possible. We expect our current mitigation efforts for these specific issues to complete within the the two to three hours. As we progress with these mitigation efforts, customers will observe higher success rates for these operations. Additionally, we are investigating ways to speed up these specific mitigation efforts, but are ensuring we do so safely. As of this time, power restoration is still several hours away. We will provide another update by 5:30 PM PST, or sooner if we have additional information to share.
investigating
We are seeing significant signs of recovery for AssociateAddress requests, and continue to work toward fully mitigating this issue. This combined with the earlier recovery of the AllocateAddress API means customers can now successfully create and associate new network addresses in the unaffected AZs. Other AWS Services are also now observing sustained improvement as a result of the EC2 Networking APIs recovery. We are now focusing on implementing a change that will allow customers to Disassociate Elastic IP addresses from resources that are impacted by the underlying power issue. We expect this specific mitigation to take another hour to complete. We do not have an ETA for power restoration at this time. For customers that can, we recommend using alternate Availability Zones or other AWS Regions where applicable. We will provide another update by 6:30 PM, or sooner if we have additional information to share.
investigating
We confirm the recovery of the AssociateAddress API requests. We have also applied a change that enables customers to disassociate Elastic IP addresses from resources that are impacted by the underlying power issue. With these mitigations, customers can now successfully create and associate new network addresses in the unaffected AZs as well as re-associate Elastic IPs from resources in the affected zone to resources in the unaffected zones. We still do not have an ETA for power restoration at this time. For customers that can, we recommend using alternate Availability Zones or other AWS Regions where applicable. We will provide another update by 10:00 PM, or sooner if we have additional information to share.
investigating
We are investigating additional connectivity issues and error rates in the ME-CENTRAL-1 Region.
investigating
We can confirm that a localized power issue has affected another Availability Zone in the ME-CENTRAL-1 Region (mec1-az3). Customers are also experiencing increased EC2 APIs and instance launch errors for the remaining zone (mec1-az1). At this point it is not possible to launch new instances in the region, although existing instances should not be affected in mec1-az1. Other AWS Services, such as DynamoDB and S3 are also experiencing significant error rates and latencies. We are actively working to restore power and connectivity, at which time we will begin to work to recover affected resources. As of this time, we expect recovery is multiple hours away. For customers that can, we recommend failing away to another AWS Region at this time. We will provide an update by 12:00 AM PST, or sooner if we have additional information to share.
investigating
We continue to work on a localized power issue affecting multiple Availability Zones in the ME-CENTRAL-1 Region (mec1-az2 and mec1-az3). Customers are experiencing increased EC2 API errors and instance launch failures across the region, and it is not currently possible to launch new instances; existing instances in mec1-az1 should not be affected. Amazon DynamoDB and Amazon S3 are also experiencing significant error rates and elevated latencies. We are actively working to restore power and connectivity, after which we will begin recovery of affected resources; full recovery is still expected to be many hours away. We recommend that affected customers failover, and backup any critical data, to another AWS Region. We will provide an update by 2:00 AM PST, or sooner if the situation changes.
investigating
We wanted to provide more information on Amazon S3 given that there are two impaired Availability Zones (mec1-az2 and mec1-az3) in the ME-CENTRAL-1 Region. Amazon S3 is a regional service and designed to withstand the total loss of a single Availability Zone while maintaining S3's durability and availability. When the mec1-az2 AZ was powered off at approximately 4:00 AM PST on Sunday, March 1, S3 continued to operate normally. As the second AZ became impaired, S3 error rates increased. With two Availability Zones significantly impacted, customers are seeing high failure rates for data ingest and egress. We strongly advise customers to update their applications to ingest S3 data to an alternate AWS Region. As soon as practically possible, we will begin the restoration of our two Availability Zones which will include a careful assessment of data health and any repair of storage if necessary.
In addition, we can confirm that the AWS Management Console and command line interface (CLI) are disrupted by the failure of two Availability Zones. We continue to work towards recovery across all services, and we will provide an update by 6:00 AM PST on March 2, or sooner if we have additional information to share.
investigating
We continue to work towards recovery of the two impaired Availability Zones (mec1-az2 and mec1-az3) in the ME-CENTRAL-1 Region. We are expecting recovery to take at least a day, as it requires repair of facilities, cooling and power systems, coordination with local authorities, and careful assessment to ensure the safety of our operators. EC2, Amazon DynamoDB and other AWS Services continue to experience significant error rates and elevated latencies.
We recommend customers enact their disaster recovery plans and recover from remote backups into alternate AWS Regions, ideally in Europe. Further, we strongly advise customers to update their applications to ingest S3 data to an alternate AWS Region. We will provide an update by 11:00 AM PST on March 2, or sooner if we have additional information to share.
investigating
We continue to work towards recovery of the two impaired Availability Zones (mec1-az2 and mec1-az3) in the ME-CENTRAL-1 Region. The impact is causing elevated errors rates for both the Management Console and CLI. Our current expectation is that recovery will take at least a day to complete. We continue to recommend customers enact their disaster recovery plans and recover from remote backups into alternate AWS Regions. We will continue to provide periodic updates on recovery efforts. Our next update will be by 2:00 PM PST or sooner if new information becomes available.
investigating
We continue to work towards recovery of the two impaired Availability Zones (mec1-az2 and mec1-az3) in the ME-CENTRAL-1 Region. We have partially restored access to the AWS Management Console, however, some pages will continue to load unsuccessfully until we have recovered core services and power. In parallel to the power and recovery efforts, we are working to restore access to tools and utilities to allow customers to backup and migrate their data. We have no updated guidance on expected recovery times, and still expect this to take at least a day to fully restore power and connectivity. We continue advising customers enact their disaster recovery plans and recover from remote backups into alternate AWS Regions. We will provide you with another update by 6:00 PM PST, or sooner if new information becomes available.
investigating
We are providing an update on the ongoing service disruptions affecting the AWS Middle East (UAE) Region (ME-CENTRAL-1) and the AWS Middle East (Bahrain) Region (ME-SOUTH-1). Due to the ongoing conflict in the Middle East, both affected regions have experienced physical impacts to infrastructure as a result of drone strikes. In the UAE, two of our facilities were directly struck, while in Bahrain, a drone strike in close proximity to one of our facilities caused physical impacts to our infrastructure. These strikes have caused structural damage, disrupted power delivery to our infrastructure, and in some cases required fire suppression activities that resulted in additional water damage. We are working closely with local authorities and prioritizing the safety of our personnel throughout our recovery efforts.
In the ME-CENTRAL-1 (UAE) Region, two of our three Availability Zones (mec1-az2 and mec1-az3) remain significantly impaired. The third Availability Zone (mec1-az1) continues to operate normally, though some services have experienced indirect impact due to dependencies on the affected zones. In the ME-SOUTH-1 (Bahrain) Region, one facility has been impacted. Across both regions, customers are experiencing elevated error rates and degraded availability for services including Amazon EC2, Amazon S3, Amazon DynamoDB, AWS Lambda, Amazon Kinesis, Amazon CloudWatch, Amazon RDS, and the AWS Management Console and CLI. We are working to restore full service availability as quickly as possible, though we expect recovery to be prolonged given the nature of the physical damage involved.
In parallel with efforts to restore the physical infrastructure at the affected sites, we are pursuing multiple software-based recovery paths that do not depend on the underlying facilities being fully brought back online. For Amazon S3 and Amazon DynamoDB, we are actively working to restore data access and service availability through software mitigations, including deploying updates to enable S3 to operate within the current infrastructure constraints and remediating impaired DynamoDB tables to restore read and write availability for dependent services. Our focus on restoring these foundational services is deliberate, as recovery of Amazon S3 and Amazon DynamoDB will in turn enable a broad range of dependent AWS services to recover. For other affected service APIs, we are deploying targeted software updates to reduce error rates and restore functionality where possible, independent of the physical recovery timeline. We are also working to restore access to the AWS Management Console and CLI through network-level changes that route traffic away from the affected infrastructure. While these software-based mitigations can address many of the service-level impacts, some recovery actions are constrained by the physical state of the affected facilities — meaning that full restoration of certain services will require the underlying infrastructure to be repaired and brought back online. Across all services, our teams are working in parallel on both the physical restoration of the affected facilities and these software-based mitigations, with the goal of restoring as much customer access as possible as quickly as possible, even ahead of full infrastructure recovery. In addition, we are prioritizing the restoration of services and tools that enable customers to back up and migrate their data and applications out of the affected regions.
Finally, even as we work to restore these facilities, the ongoing conflict in the region means that the broader operating environment in the Middle East remains unpredictable. We recommend that customers with workloads running in the Middle East consider taking action now to backup data and potentially migrate your workloads to alternate AWS Regions. We recommend customers exercise 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 will continue to provide updates as recovery progresses and as the situation evolves. Our next update will be provided by 9:00 PM PST on March 2, 2026, or sooner if new information becomes available.
investigating
We continue to work towards recovery of the two impaired Availability Zones (mec1-az2 and mec1-az3) in the ME-CENTRAL-1 Region with a focus on restoring functionality to foundational services. Since our last update we have made incremental progress in recovering the DynamoDB control plane which will not be visible to external customers but are required for the restoration of service. Similarly we have made progress with the S3 control plane. The recovery of these foundational services, when complete, will enable a broad range of dependent AWS services to recover. We still estimate that the recovery time is at least a day before we are able to fully restore power and connectivity. We will provide you with another update by March 3 2:00 AM PST, or sooner if new information becomes available.
investigating
We are providing an update on the ongoing service disruptions affecting the AWS Middle East (UAE) Region (ME-CENTRAL-1). The overall state of the region remains largely unchanged from our previous update. We continue to work closely with local authorities and are prioritizing the safety of our personnel throughout our recovery efforts. Teams continue to assess the damage to the affected facilities and are working to restore infrastructure impacted by the event.
With respect to Amazon S3, we are seeing improvement in PUT and LIST availability. We continue to work on improving GET error rates, but full recovery will be dependent on restoring the affected infrastructure, which our teams continue to work toward.
For Amazon DynamoDB, error rates remain elevated and our teams continue to focus on recovery efforts. We have not yet seen meaningful improvement in DynamoDB availability, but expect conditions to improve over the coming hours as recovery work progresses.
Amazon EC2 instance launches remain throttled in the ME-CENTRAL-1 Region. We will begin relaxing these throttles as soon as we have fully recovered our foundational services and have sufficient capacity to support new launches safely.
The AWS Management Console is now operational, though customers may continue to experience errors on certain pages and operations as the underlying services work through their recovery. We recommend customers continue to retry requests where possible.
AWS Lambda, Amazon Kinesis, Amazon CloudWatch, Amazon RDS, and a number of other AWS services that were impacted by this event remain degraded. The availability of these services is dependent on the recovery of our foundational services — primarily Amazon S3 and Amazon DynamoDB — and we expect to see improvement across these services as that recovery progresses.
Finally, even as we work to restore these facilities, the ongoing conflict in the region means that the broader operating environment in the Middle East remains unpredictable. We 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 will continue to provide updates as recovery progresses and as the situation evolves. Our next update will be provided by 5:00 AM PST on March 3, or sooner if new information becomes available.

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.

resolved
We are experiencing intermittent missing or delayed EC2 instance and status check metrics in the US-EAST-1 Region. Alarms on delayed or missing metrics may transition into an INSUFFICIENT_DATA state. We are taking multiple parallel paths to mitigate this issue. While underlying resources are not affected by this issue, customers with automated actions based off of delayed or missing metric data may see their automations start. EC2 APIs are not impacted and therefore EC2 AutoScaling will not be affected by this issue.
resolved
We can confirm issues with intermittent missing and/or delayed EC2 instance metrics and status checks in the US-EAST-1 Region. While existing instances are unaffected by this issue and operating normally, metrics and status checks may be delayed or reporting INSUFFICIENT_DATA. We have identified the issue to be in an underlying subsystem responsible for publishing EC2 metric data to CloudWatch. Engineers were automatically engaged, and continue to investigate multiple paths to mitigate the issue in parallel. We recommend customers treat the INSUFFICIENT_DATA state as missing data instead of an alarm breach, especially when configuring the alarm to stop, terminate, reboot, or recover an instance. More information is available <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/UsingAlarmActions.html">here</a>. While we do not have a firm ETA for resolution, we will provide another update by 12:30 PM, or sooner if we have additional information to share.
resolved
We are seeing early signs of recovery and continue to work toward full resolution. We will continue to provide updates.
resolved
We can confirm significant signs of recovery, and continuing to monitor to ensure stability. At this time, missing/delayed metrics and instance status checks are recovered. We are actively working to backfill delayed data.
resolved
Between 7:00 AM and 12:05 PM PST, we experienced errors while publishing EC2 instance metrics and status checks in the US-EAST-1 Region. This issue resulted in metrics and status checks to be delayed or report INSUFFICIENT_DATA. EC2 APIs and instances were unaffected by this issue and continue to operate normally.
We were automatically engaged at 7:05 AM and began identifying multiple parallel paths to mitigate the issue. By 7:20 AM, we identified that the issue was related to an underlying subsystem responsible for publishing EC2 metric data to CloudWatch. By 12:03 PM, we completed our mitigation efforts and observed full recovery at 12:05 PM. New metrics are being published as expected. Delayed metrics are in the process of backfilling and may take a few hours to fully complete. The issue has been resolved and the service is operating normally.
