Re: The data loss was in one of three zones available
I agree.  You would think that if you are promoting a service that is supposed to be up almost 100% of the time, that you have proper failovers in place.  The sad reality is that often unless they are spread out, replicated in another site, or can react quick enough to failover, it's almost impossible to respond to something like lightening which is sadly really unpredictable.  Nonetheless, it's just another great reason organizations should use replication incase the main data site gets interrupted.

Re: The data loss was in one of three zones available
It surprises me that backup systems fail to work for the one job they wait for. As I recall, there was a SF-based ISP a few years back that had a failure and its backup generators failed to work as expected. Failover switching ought to be more reliable.

The data loss was in one of three zones available
To prevent data loss, Google, like other cloud providers, recommends keeping a back up system in a second zone. At Ghislain, it has three zones available: Europe-West1-b, Europe-West1-c and Europe-West1-d. The disks affected were in West1-b. Drives in c and d remained unaffected and would have provided a quick recovery if customers had replicated systems and data flows there.
