Data is automatically distributed across a minimum

Designed for 99.999999999% durability and 99.99%
availability of objects over a given year.
Designed to sustain the concurrent loss of data in two facilities.

Uptime: 99.9% SLA
Reliability: 99.999999% durability
So S3 is 10x more available, 1000x more durable, and datacenter redundant.
- shawn-furyan 9y agoEleven 9s of durability is an utterly farcical guarantee from a decade old service. A single big durability event in the next century would irrevocably decimate that record. They really might as well claim 100% durability, because it is no less plausible. I mean, what are the odds that S3 will even be operating in 100 years? I'll certainly put $1 against $1,000,000,000 that it won't, and that's only one many ways it could fail the standard.
