Sounds like this wasn't caused by power surges reaching the equipment but rather an effect of repeated power loss to drive arrays not fully designed to handle it. The article is pretty unclear. Still sounds like an infrastructure problem though.

This could potentially explain a lingering error on my Google Drive. Might there be movement within Google to contact the owners of data that was lost?

The article mentions Compute Engine, which is an external offering that isn't really used internally. It's hard to say what else might have been affected, if anything, but going by the article this shouldn't be causing your problem.

Beyond security, this highlights one of the main issues with the cloud. Was there no backup? Of course once you get beyond the headline, I think most people are much worse with protecting themselves from rare outages than Google.

The article states that it was "some recently written data [...] located on storage systems which were more susceptible to power failure". Perhaps it hadn't made it to a backup.

You find more details in the Google incident report: https://status.cloud.google.com/incident/compute/15056#57195...

Fair enough. One can hope.

As mentioned in the article, it only affected recently written data of 'Google Compute Engine' services. GCE allows user to launch VMs and generate arbitrary data on the server.

Normally, Google redundantly distributes out data to at least 3 different geographically distinct locations. Check out the 'BigTable' white paper [0] for more info.

For 99% of cases (and pretty well all user cases), this would not cause data lose. The key here is that the data was generated on the servers and did not have a chance to duplicate before the event.
