Is Amazon Elastic Compute Cloud down?
Current Amazon Elastic Compute Cloud status is UP

We are investigating increased delays in EC2 instance and Status Check metrics, including DescribeInstances and DescribeInstanceStatus API results, in a single Availability Zone (use2-az1) in the US-EAST-2 Region. During this time, some alarms on delayed metrics may transition into an INSUFFICIENT_DATA state. Existing instances are not affected.

We are investigating increased API error rates for the EC2 APIs in the US-EAST-1 Region. This is mainly affecting the DescribeInstanceTypes, DescribeInstanceTypeOfferings and DescribeReservedInstancesOfferings APIs. During this time, customers may receive an Internal Error displayed in the Management Console under the "Instance Types" section. We are actively working on identifying the root cause. We will provide another update by 2:30 PM PST, or sooner if we have additional information to share.

We continue to investigate increased error rates and latencies for the DynamoDB APIs in the US-WEST-2 Region. We have seem some improvement in error rates over the last 15 minutes but customers may still be experiencing errors. We continue to work on resolving the issue and will keep you updated on our progress.

We are investigating increased error rates and increased delays in network propagation for newly launched EC2 instances in a single Availability Zone (use-az2) in US-EAST-1 Region. EC2 System Status Check metrics may also be reporting “INSUFFICIENT_DATA” state for the affected instances. The issue does not affect networking connectivity for existing instances and we are working to resolve the issue.

We continue to progress toward resolving the increased networking latencies and errors affecting Availability Zones (usw2-az1 and usw2-az2) in the US-WEST-2 Region. At this time, we are approximately 50% completed with the update to address resource contention within the subsystem responsible for network mappings propagation in the usw2-az2 Availability Zone. Once we complete the update in usw2-az2, we will then move on to usw2-az1. Our current expectation is to have both Availability Zones fully resolved within the next 60 to 90 minutes, and we will continue to provide updates as recovery progresses.
