We have identified that the degraded AWS CloudWatch integration is caused by an ongoing AWS disruption in the me-central-1 (UAE) region, including AWS CloudWatch and the Resource Groups Tagging API. Customers with AWS resources in this region may see missing or outdated resource tags on AWS metrics, and metric stream configuration changes may not be applied. Metric ingestion is not impacted. AWS has not provided a recovery timeline and recommends migrating to another region.
