Where are Heroku apps hosted exactly?

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 fin

Answer 1

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",
    "id": "ed30241c-ed8c-4bb6-9714-61953675d0b4",
    "locale": "Dublin",
    "name": "eu",
    "private_capable": false,
    "provider": {
      "name": "amazon-web-services",
      "region": "eu-west-1"
    },
    "updated_at": "2016-08-09T22:03:28Z"
  },
  {
    "country": "United States",
    "created_at": "2012-11-21T20:44:16Z",
    "description": "United States",
    "id": "59accabd-516d-4f0e-83e6-6e3757701145",
    "locale": "Virginia",
    "name": "us",
    "private_capable": false,
    "provider": {
      "name": "amazon-web-services",
      "region": "us-east-1"
    },
    "updated_at": "2016-08-09T22:03:28Z"
  }
]

Answer 2

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 3

Regin EU details :

Country -> Ireland
City -> Dublin
AWS Region -> eu-west-1

Region US details :

Country -> United States
City -> Virginia
AWS Region -> us-east-1

Answer 4

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",
  "created_at":"2012-11-21T20:44:16Z",
  "description":"United States",
  "id":"59accabd-516d-4f0e-83e6-6e3757701145",
  "locale":"Virginia",
  "name":"us",
  "private_capable":false,
  "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.
