Resumo
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.
