title: Where are Heroku apps hosted exactly?
body: <p>Through <a href="https://devcenter.heroku.com/articles/regions" rel="noreferrer">https://devcenter.heroku.com/articles/regions</a> I see that for heroku common runtime spaces heroku has two available regions: Europe and United States. But I couldn't find exactly in any official documentation which region exactly of United States heroku hosts the application. For example I want to know if it hosts on east, west, north, south.</p>
  
  <p>Thanks</p>
