Scale of impact, scope of impact, and duration of impact are orthogonal. Conflating them makes productive discussion impossible, IMO.

But back to the point, philosophically I agree, but practically I don't. IMO having SLA's and enforceable guarantees that give customers the information they need is much harder than exposing the implementation details.

"Zones within a region may be located in the same building" is much more concise than SLA's using contractual language, and probably conveys more (though potentially less accurate) information once I apply my context.

Also, if we look GCP's SLA's, this outage blew the SLA breach threshold out of the water for many services. Some are pushing 2 9's of downtime from this incident alone.

Finally (in hindsight maybe I should have led with this, but I'm too lazy to restructure this comment), SLA's are a joke. Outages can destroy your business, but all you get from your cloud provider is that they comp you for usually a small fraction of what they charge you. They have no teeth, so if you can't just write off a major outage you have to have a plan to avoid it, which means you need to know the implementation details
