I’ve had phenomenally good support from AWS. I recently had a problem where a nat instance was opening more than 55k simultaneous connections (don’t ask) and AWS support helped me track down which ecs service it was coming from. I’ve had utter shit support from GCP (mostly around “hey can I get this API limit raised). My best support from GCP was from our customer evangelist. He actually knew stuff. His turnaround time was 3-5 days. I eventually just stopped filing support cases because they were useless.
