Monitoring
AWS reports that recovery is progressing in the US-EAST-1 region. Their mitigations are showing early signs of success in several Availability Zones, with remaining AZs being addressed. We are observing gradual improvement in network stability and expect the intermittent connection issues to subside as AWS completes their recovery process.

Identified
Additionally, data integration connectors and extended authentication services that depend on external resources in us-east-1 may experience intermittent timeout errors. This particularly affects configurations using AWS managed services such as Network Load Balancers, DynamoDB, Lambda, InfluxDB, and other endpoints hosted in the us-east-1 region.

Investigating
AWS has confirmed network connectivity issues in the US-EAST-1 region affecting multiple services. While AWS reports early signs of recovery, we are observing continued network instability that may impact EMQX Cloud deployments in this region.
Please ensure your MQTT clients have automatic reconnection logic enabled. Clients with proper reconnect mechanisms will automatically restore connections without data loss. Most standard MQTT client libraries have this capability built-in by default.
