Standalone NAT gateway lacks HA for egress routing #120

Closed davidwadden closed 4 years ago

davidwadden commented 5 years ago

Per the NAT Gateway docs, the current routing through a standalone NAT gateway in the non-"Internetless" configuration creates a dependency for egress routing on the first availability zone. In the event that AZ1 goes down, the remaining AZ's will go offline.
