The point of signing contracts is you explicitly set expectations for service, and explicitly assign liability. You can't just reverse that and try to pass the blame.

Sure, if someone from GCP shows up at your business and breaks your leg or burns down your building, you can go after them, as it's outside the reasonable expectation of the business agreement you signed.

But you better believe they will never be legally responsible for damages caused by outages of their service beyond what is reasonable, and you better believe "reasonable outage" in this case is explicitly enumerated in the contact you or your company explicitly agreed to.

Sure they might give you free credits for the outage, but that's just to stop you from switching to a competitor, not any explicit acknowledgement they are on the hook for your lost business opportunity.

"Can" isn't the same as "is"
