Starting at 11:24 AM PST, some load balancers in the USE1-AZ2, USE1-AZ4, and USE1-AZ5 Availability Zones experienced connectivity issues when terminating TLS (SSL) connections in the US-EAST-1 Region. Engineers worked to identify the root cause of the event, ultimately deploying an update to recover USE1-AZ4 at 1:50 PM PST, USE1-AZ2 at 4:26 PM PST and USE1-AZ5 at 4:31 PM PST. Network Load Balancers not terminating TLS (SSL) connections were not affected by this event. Some PrivateLink endpoints were also affected by the issue. The issue has been resolved and the service is operating normally.
