We continue to work towards resolving the issue affecting connectivity for instances within a single Availability Zone (USGW-AZ3) in the US-GOV-WEST-1 Region. We have identified the root cause of the issue and are now focused on mitigating the issue. We are seeing some recovery in the error rates and latencies for the EC2 APIs and launches of new instances are once again working within the region. For recovery at this stage, we recommend focusing on shifting workloads and traffic away from the affected Availability Zone (USGW-AZ3).
