> 1. All billing metrics are stored in us-east-1 even for usages in other regions.

...what? Is this true? If so, can someone explain the logic behind this?

[ceejayoz]

It's true, and probably means a set of instances in us-east-1 are the ones computing and storing billing costs for users.

Doing so allows customers to easily view the total estimated spend, rather than having to go to each region and add it up.
