AWS promises to keep data safe without requiring cross region redundancy. If you choose not to trust them that's valid but then why use them at all?

>> AWS promises to keep data safe without requiring cross region redundancy.
A perfect example of a claim they never made.
You'd be surprised how many customers are lead to believe this by a combination of opaque marketing, aggressive sales, and willful ignorance.
I worked at a 2000 person shop where the CTO moved us from 1 on-prem dc (we were begging to add a secondary site for years due to outage risk) to 1 AWS region.
It's not exactly straightforward to run multi-region across an alphabet soup of AWS services without decent configuration / application awareness, paying at least double.
S3 is advertised as having 11 9's. That means in the entire history of S3 they've only lost a handful of objects, and will continue to lose objects at this same rate.
You are confusing the concepts, and applying the 11 nines to the wrong problem.
Durability is about: "If I successfully store an object in S3, how unlikely is S3 to permanently lose that object because of storage failures?"
It does not answer: "Will I be able to access that object, after a rain of Shahab-1 or Shahab-2 burn all data centers in the 3 availability regions across which my S3 bucket is spread out..."
