I suppose it's possible but S3 is designed for nine 9's wrt to durability. There are > 100 billion objects and I'm not aware of any being lost due to AWS fault.

Actually, I'm wrong. It's eleven 9's. http://bit.ly/ageV9D

Also curious to know of any S3 bucket failure stories out there. I would assume this is uncommon, but I also assumed that the EBS failure rate was much lower prior to reading this.
