What's the cloud solution (at major providers) that automatically geographically replicates data? For example, S3 buckets are tied to a region, which cannot be considered reliable - a single DC can always burn down, or even just intermittently unreachable. I'm looking for something that accepts an "upload" command that will (eventually) replicate the data to several regions. Ideally the regions can be changed at any point later, too.

This would take care of 3 and 1, sadly not 2 but 2 is pretty hard.
