My read on the situation is Yet Another Intermediate Cacheing Fail in storage, 
a well known problem.  Yes, do a pull the power test on your storage so you 
KNOW what's committed...

This was data loss on GCE persistent disks (equivalent to AWS EBS), not
archival storage.  Hopefully very few people are using persistent disks as
*backup* storage (if nothing else, it's more expensive).

The general point is still valid, though -- *any* single instance of data is
vulnerable to loss, whether it's on your computer, or someone else's. 
Backups are never optional.

Love the phrasing too - permanently lost access to their data. Their
data is not lost, not gone, not destroyed, oh no! It's still there,
somewhere, but they will just never, ever be able to access it again.

Maybe it's to leave a sliver of hope: We'll meet again, don't know
where, don't know when, but I know we'll meet again (all together now,
customers!) some sunny day...
