S3 has touted 11 9's for many years, so before shardstore definitely.
The 11 9's is for durability, which is really more about the redundancy setup, erasure coding, etc. (https://cloud.google.com/blog/products/storage-data-transfer/understanding-cloud-storage-11-9s-durability-target https://cloud.google.com/blog/products/storage-data-transfer...)
