They only have big outages. The VMs are incredibly reliable other than the big incidents. And, as I am often reminded by my product owners, people don't mind big outages as much as much as small random failures. If the whole thing is down, ok, fine, I'll go home. If it fails 0.1% all the time, my life is suffering. And in GCP, you start a VM and it just stays up. We've killed them from inside with memory leaks and filling the disk etc., but I haven't seen GCP kill them (50K VMs for couple years).
