Heroku only has two regions, Europe and US. Many applications not targetting the American market are still hosted on the US region. For instance, I live in Japan, and all the heroku applications I know of are hosted in the US region. Additionally, as I understand it, most of Heroku's resources are used by a small number of large, international services, who's usage times don't necessarily correspond to USA hours.
