This isn’t a whole-cloud outage. It’s not even a whole-region outage.

Whole-cloud outages are pretty damn rare. The recent GCP issues are an exception to the general rule.

I’d posit that the complexity of a multi-cloud setup is generally going to reduce your service’s reliability more than relying on a single cloud does.

Not about regions, it’s about services

Whole-zone outages are also rare...

"Rarity" is a distinction without merit in this particular case; the important thing to note is that (most) clouds don't guarantee _any_ availability of a single zone. A system which stashes all of its infrastructure in one zone only is expected to be impacted by issues with that cloud, while a multi-zone setup spanning a region is generally "soft-guaranteed" to be resilient to normal operations / failures.

Really?

AWS (EC2) does: https://aws.amazon.com/compute/sla/?did=sla_card&trk=sla_car... so does GCP (GCE): https://cloud.google.com/compute/sla?hl=en and so does OVH: https://us.ovhcloud.com/legal/sla/public-cloud/

Are none of those three part of "most clouds"? What cloud platform do you use?
