> Amazon's S3 for example offers a 99.999999999% data durability guarantee
IIRC AWS S3 was subjected to formal methods design using TLA+, so as long as the underlying infrastructure is correctly implemented, I suspect the durability guarantee is on fairly solid foundations.
Also of course, I suspect the durability guarantee is based on what option you select for your bucket in the S3 console.
