AWS Service Update – Service is operating normally: [RESOLVED] Increased Faults and Latencies

Between 09:15 AM and 10:51 AM PST, some customers experienced elevated faults when calling CloudWatch Metrics PutMetricData and CloudWatch Logs PutLogEvents APIs in the AP-EAST-1 Region. Some metrics were delayed, CloudWatch alarms on delayed metrics transitioned into INSUFFICIENT_DATA state, and some metric data may be missing. The issue is resolved and the service is operating normally.
