If there's confusion about the concept of regions, it seems to be coming from Amazon themselves. They couldn't just call it the Ohio region?

Is that really an issue? Sometimes I get the number suffixes confused (like us-west-1 and us-west-2). Additionally, would you refer to the Sydney region or the New South Wales region?

For people from outside of North America, "us-east-2" is far more informative than "Ohio".
