This is why Microsoft calls it an Availability Zone, each zone is made up of one or more data centers equipped with entirely independent power, cooling, and networking infrastructure. One zone should not knock out other zones. Zones are also often nearby each other just enough that they have very efficient fiber optic connections between them.
That said, that's how Microsoft handles it, I'm not sure how GCP compares.
It is an interesting conundrum though, what if all your nearby availability zones come down at once due to power loss? I wonder which major cloud provider has the best setup for these sort of events.
GCP has some regions where all of the AZs are located in the same physical building. AFAIK they’ve stopped doing this in newer regions and have been migrating existing regions to have physically separate sites for each AZ.
AWS has always guaranteed that different AZs are physically separate sites, but that hasn’t always been the case with GCP.

im only familiar with microsoft in this sense, but they have "geo-zone-redundant storage" which copies data across 3+ availability zones in the primary region, and also a secondary geographic region (i think at least 100 miles away if i remember, but maybe further). any incident would have to be massive to affect multiple geo-zones
