I can't confirm that, they are providing good support as a sales tactic, rather than because of our spend. To clarify: I don't have first-hand experience with their support, but I've heard from colleagues that it's been fine.

I've had awful support. They reached out to me after I had an issue two months ago and CC'd 6 engineers but then stopped responding to my emails when it time to actually schedule time to "discuss my architecture". I tweeted about this, @GoogleCloud responded instantly, promised they would poke their support people. That was a week ago and I have heard nothing since. I've sent three follow-up emails.

Same here but based on AWS experience going from 50k a year place to many millions per month of AWS spend resulted in very drastic change in support level and access to senior tech people when needed. I would imagine someone who really moves the needle like Netflix gets unprecedented level of access.
