[Monitoring] Automatic scaling services could be hampered after the following AWS Health update:
[03:35 AM PDT] The underlying DNS issue has been fully mitigated, and most AWS Service operations are succeeding normally now. Some requests may be throttled while we work toward full resolution. Additionally, some services are continuing to work through a backlog of events such as Cloudtrail and Lambda. While most operations are recovered, requests to launch new EC2 instances (or services that launch EC2 instances such as ECS) in the US-EAST-1 Region are still experiencing increased error rates. We continue to work toward full resolution. If you are still experiencing an issue resolving the DynamoDB service endpoints in US-EAST-1, we recommend flushing your DNS caches. We will provide an update by 4:15 AM, or sooner if we have additional information to share.
