Is it not possible that they own their own data center and have an unfortunate Google dependency?
Obviously a fiasco but I’m not prepared to call them liars when it could be an honest mistake.
I imagine there's also an important difference between:
1. We depend on X but could gracefully migrate to an alternate in a week if we really needed to.
2. All data is mirrored instantly so that we can do seamless fail-over in case X has its own outage.
Then don't say your not a "Cloud on top of a cloud" provider.
They even made fun of cloud providers being down when AWS was down.
