					[RESOLVED] Increased API Error Rates 6:21 AM PDT We have identified the cause of the increased API error rates in a single Availability Zone in the US-EAST-1 Region and continue working towards resolution. Customers experiencing errors launching new EC2 instances may attempt to launch their EC2 instances in another Availability Zone. Existing running instances are unaffected. 8:23 AM PDT We want to provide more information on this issue and progress toward resolution. At 5:18 AM PDT, we began experiencing increased API errors that originated from one of our EC2 sub-systems that is responsible for managing EC2 instances. This resulted in increased error rates for some EC2 APIs and affected new instance launches in a Single Availability Zone. The root cause of the error rates affecting the sub-system has been identified and engineers are currently working on resolving the issue. Existing instances remain unaffected by this issue. 10:19 AM PDT We have deployed a fix to the impacted EC2 sub-system causing increased API error rates and new instance launch failures in a Single Availability zone in the US-EAST-1 Region and are beginning to see recovery. We continue to work towards full resolution. Existing instances remain unaffected by this issue. 10:52 AM PDT Between 5:18 AM and 10:25 AM PDT we experienced increased error rates for some EC2 APIs and new instance launches in a Single Availability Zone in the US-EAST-1 region. Existing instances were unaffected. We are working to address API errors affecting a small number of EBS volumes as a result of this issue. The issue has been resolved and the service is operating normally.





























































































































































						[RESOLVED] Single AZ Intermittent DNS Lookup 2:11 AM PDT We are investigating an increase in DNS lookup failures from EC2 instances in a single Availability Zone in the US-EAST-1 Region. 2:57 AM PDT We are continuing to investigate increased DNS resolution errors from EC2 instances in a single Availability Zone of the US-EAST-1 Region. This could also impact functionality of other services that use EC2, such as App Mesh, Cloud9, ElasticSearch, EMR, Managed Blockchain, SageMaker, Transfer for SFTP, WorkMail, and Glue. 3:44 AM PDT We are implementing a mitigation to the increased DNS resolution errors from EC2 instances in a single Availability Zone in the US-EAST-1 Region, and are starting to see recovery. This issue could also impact functionality of other services that use EC2, such as App Mesh, Cloud9, ElasticSearch, EMR, Managed Blockchain, SageMaker, Transfer for SFTP, WorkMail, RDS, and Glue. 4:19 AM PDT DNS resolution failures in a single Availability Zone in the US-EAST-1 Region have largely been mitigated, and we are continuing to work towards full mitigation. 4:37 AM PDT Between 1:22 AM and 4:13 AM PDT, customers experienced an increase in DNS resolution errors from EC2 instances in a single Availability Zone of the US-EAST-1 Region. This could have also impacted functionality of other services that use EC2, such as RDS, SageMaker, EMR, WorkMail, MSK, AWS IoT Analytics Service, Amazon ElasticSearch, Cloud9, AppMesh, Amazon Managed Blockchain, Glue, and AWS Transfer. The issue has been resolved and all DNS queries are being answered normally.
