Google do actually offer great support, I pay like $30 a month for it and I can speak with real engineers who give super detailed answers.
It’s just not free. But the paid offering is great in my experience.
At least it isn't (paid) Azure Support - that one is noticeably outsourced to people that sometimes lack basic comprehension for the problem. I once asked about their VPN Gateway and got a random API Gateway response, then nothing for a week, and then a new rep.
Honestly, it boggles my mind. Bad marketing seems to be the driving force here.
“Nobody ever gets fired for buying IBM.”
If you've actually spent time building on their platform though, it feels like you're in some sort of inner circle of knowledge. The stuff works, and works really well.
