As part of our ongoing plan to expand the AWS footprint, I am happy to announce that our new US East (Ohio) Region is now available. In conjunction with the existing US East (Northern Virginia) Region, AWS customers in the Eastern part of the United States have fast, low-latency access to the suite of AWS infrastructure services.

Low latency to US East (Virginia) should provide an opportunity to try out some cross region experimentation to work on fault tolerance and high availability.
