title: AWS Certificate Manager - Do regions matter?
body: <p>I already have a certificate from AWS Certificate Manager (ACM) when only the 1 region was available (think the US-West-1 region?) and currently being used with Cloudfront to host a website for the Australian market.</p>
  
  <p>Now that ACM is <a href="https://aws.amazon.com/about-aws/whats-new/2016/05/aws-certificate-manager-now-available-in-more-regions/" rel="noreferrer">available in more regions</a>, would using a certificate created from the Sydney region have any improvements in performance? </p>
