Doesn’t really apply, because the only reason data was lost is because customers chose not to replicate it to other regions, either because of legal data residency requirements, cost, or just not bothering.
If Skynet wants to make sure it’s backed up, none of that prevents it from doing so. Although it would be amusing if Skynet was stopped by a billing alert when it tries to copy itself to another region.

- Betelbuddy 19d ago>> AWS promises to keep data safe without requiring cross region redundancy. A perfect example of a claim they never made.
- mitxela 19d agoS3 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.
- Betelbuddy 19d agoYou 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..."

- antonvs 19d agoEleven nines covers ordinary infrastructure failures, not acts of war that physically destroy the underlying facilities. It's similar to any engineered artifact, like a skyscraper. They have a structural safety factor that defines their resilience to failures that the system is designed to tolerate, it doesn't make them immune to missile strikes.

- steveBK123 19d agoYou'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.
