When things stop working, GCP is the worst. Slow communications and they require way too much work before escalating issues or attempting to find a solution.
They already have the tools and access so most issues should take minutes for them to gather diagnostics, but instead they keep sending tickets back for "more info", inevitably followed by a hand-off to another team in a different time zone. We have spent days trying to convince them there was an issue before, which just seems unacceptable.
I can understand support costs but there should be a test (with all vendors) where I can officially certify that I know what I'm talking about and don't need to go through the "prove its actually a problem" phase every time.
