We have seen no further network connectivity issues for NAT Gateway since 1:45 PM PST (5 hours ago). We have identified the root cause and prepared a fix to resolve the issue, which is now being deployed. We have also taken steps to mitigate any impact should the issue reoccur before the deployment is fully completed. This issue resulted in two periods of network connectivity issues between 11:30 AM and 12:00 PM PST, and between 1:00 PM and 1:45 PM PST. The issue has been resolved and the service is operating normally.
