Their cloud offerings are a distant third to Microsoft and Amazon and support - especially enterprise support - is legendarily bad.
Also Google support is usually absent but when I actually get to talk to a human, they're great. Microsoft support is usually present but often seems explicitly designed to waste my time.
The one exception was a weird ECS error I kept getting that they couldn’t figure out. I realized later on that I hosed the permissions trying to do something cross account.
I’m sure they would have eventually figured that out.
