Between 5:50 PM and 7:15 PM PDT, we experienced connectivity issues that may have impacted Internet performance for some customers in the SA-EAST-1 Region. During this time, connectivity to instances and services within the Region was not affected. Our engineering team was automatically engaged at 5:51 PM PDT and immediately began investigating the issue. We identified the root cause and implemented a fix, which mitigated the issue at 7:15 PM PDT. The issue has been resolved and the service is operating normally.

We are investigating increased error rates for Route53 API calls.

Between 4:00 PM and 4:46 PM, we experienced increased error rates for the Route53 APIs. This issue did not impact resolution of existing DNS records. Engineers were automatically engaged and immediately began investigating the issue. During this time, customers may have received 500s for Route53 APIs and the Route53 Management Console. We have identified the root cause and have mitigated this issue. Other AWS Services that call the Route53 APIs in their workflows may also have been impacted during this time. We recommend retrying any failed operations or stuck workflows. We do not expect recurrence of this issue. The issue has been resolved and the service is operating normally.

We are investigating connectivity and power issues affecting APIs and instances in a single Availability Zone (mes1-az2) in the ME-SOUTH-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. During this time, we are also experiencing delays in propagating DNS changes for Route53 to pops (Points of Presence) in ME-SOUTH-1. Targeting new launches using RunInstances in the remaining AZs should succeed. Existing instances in the other AZs are not affected.

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.

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.
