title: Cannot create Amazon S3 Bucket in specified region
body: <p>On my macOS Sierra:</p>
  
  <pre><code>$ aws s3api create-bucket --bucket testbucket --region us-west-1
  {
      "Location": "/testbucket"
  }
  </code></pre>
  
  <p>Then...</p>
  
  <pre><code>$ aws s3api get-bucket-location --bucket testbucket
  {
      "LocationConstraint": null
  }
  </code></pre>
  
  <p>The weird thing is if I were to check my <a href="https://console.aws.amazon.com/s3/home?region=us-west-1" rel="nofollow noreferrer">console</a>, it would show my bucket created but in US East(N. Virginia region). Is the us-west-1 region not available or something?</p>
  
  <p>If it makes a difference, from 
  <code>$ aws configure</code>
  I can see that my default region name is <code>us-west-1</code></p>
  
  <pre><code>Default region name [us-west-1]:
  </code></pre>
