Where are Heroku apps hosted exactly? - heroku

Question

Through https://devcenter.heroku.com/articles/regions 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.
Thanks

Answer 1

The Heroku US region is AWS's us-east-1.
EU is eu-west-1.
That makes the US region located in North Virginia, and EU in Ireland.

Answer 2

As the URL you posted, just follow their command in your own terminal shell:
$ heroku regions --common
ID Location Runtime
── ───────────── ──────────────
eu Europe Common Runtime
us United States Common Runtime
Then use the curl as they suggest, just change the /regions/frankfurt to the region ID you want (i.e. us)
$ curl -n -X GET https://api.heroku.com/regions/us -H "Accept: application/vnd.heroku+json; version=3"
{
"country":"United States",

"provider":{
"name":"amazon-web-services",
"region":"us-east-1"
},
"updated_at":"2016-08-09T22:03:28Z"
}
Here you are: "locale":"Virginia"
Damien got you the answer, I just reconfirm if there is any changes by running all those commands.
The Heroku US region is AWS's us-east-1. EU is eu-west-1.
That makes the US region located in North Virginia, and EU in Ireland.

The other answers are great, but a simpler way to view the details about the regions is to run heroku regions --common --json, which outputs pretty formatted JSON:
[

"country": "Ireland",
"created_at": "2013-09-19T01:29:12Z",
"description": "Europe",

"provider": {
"name": "amazon-web-services",
"region": "eu-west-1"
},
