Last week's outage does look bad, and clearly would have severely impacted certain dynamic patterns of scaling, but "went down completely" does not match what's documented on that link: it prevented the creation of new GCE instances in us-east4 which required allocating/attaching new external IP addresses.
Of particular relevance to this thread, if you had a GKE cluster spun up in that region, that cluster would have continued unaffected based on that description.
GCP does have outages just like AWS does, but in recent years the impact is usually something constrained to certain products and use cases.
(Disclosure: I worked for GCP 2013-2015 but haven't worked for Google since then.)
