title: Is the S3 "US Standard" region the same as "us-east-1" in EC2?
body: <p>I am planning on running a script located on an EC2 instance in <strong>us-east-1d</strong>.</p>
  
  <p>The script basically pulls in images from a few different places and will throw them into an S3 bucket in the <strong>US-Standard Region.</strong>  </p>
  
  <p>Since there is no way to upload directly into an s3 bucket (by sending an API request that causes S3 to fetch a file from a remote URL <a href="https://stackoverflow.com/questions/7586533/is-it-possible-to-upload-to-s3-directly-from-url-using-post">as written about here</a> and I don't think this has changed) I would like to make sure that the each image I save as temp file on my ec2 will not result in additional bandwidth charges when written to S3 (ie. leaves the Amazon data center).  Will a <strong>us-east-1d</strong> EC2 instance uploading to a <strong>US-Standard S3 bucket</strong> will be communicating within the same AWS region?</p>
  
  <p>Any insight into this would be greatly appreciated as it will be terabytes of data and I'm on a shoestring bucket I'd like to know before proceeding. </p>
