Starting at 4:59 PM PDT, the AWS IAM authentication API experienced elevated error rates in the EU-NORTH-1 Region. This issue caused ELB to experience increased API error rates and latencies, as the APIs rely on the IAM service to authenticate requests. Recovery for the APIs began recovery at 5:24 PM, with full recovery at 6:11 PM. Between 6:03 PM and 6:28 PM PDT, we experienced an increase in connectivity issues and WAF errors for some load balancers. The issue has been resolved and the service is operating normally.
