This is incorrect on almost all points.

All AWS AZs are physically separated facilities with redundancy on all their infrastructure, although they're obviously in the same general area.

us-east-1 is not geo-redundant. It is entirely on the east-coast, as the name suggests. Although S3 does have geo-redundancy in all regions.

You may have been thinking of "US Standard", but it is the same as "us-east-1".

> This is a feature for EU and US-West. US Standard is bi-coastal and doesn’t have read-after-write consistency.

Their documentation is really inconsistent on this...

I've emailed Jeff to get clarification on it.
