Google Compute Engine is also an IaaS. You can also design your architecture for failure and work across multiple availability zones by using GCE. GCE is not GAE.

GCE had a multi region outage so multi zone within a region wouldn't have helped in this case.

I agree. This is the reason why this outage is more serious than others.

My mistake, mixed GCE with GAE
