To be fair AWS also has quotas on NAT Gateways.

Maximum 55k concurrent connections. After that, they make you deploy NAT gateways in other availability zones. And a max throughput of 10 Gbps.

I imagine AWS would also tell you to deploy your own gateway if you were running into the 55k concurrent connection limit of managed NAT.

AWS tends to be flexible with their quota enforcement in my experience, though.

Yea, I don't have a problem with the quota, more that the "out of quota" throttling lasts 2+ hours even after the traffic spike dies down.
