title: AWS ELB zero downtime deploy
body: <p>With an ELB setup, there as healthcheck timeout, e.g. take a server out of the LB if it fails X fail checks.</p>
  
  <p>For a real zero down time deployment, I actually want to be able to avoid these extra 4-5 seconds of down time.</p>
  
  <p>Is there a simple way to do that on the ops side, or does this needs to be in the level of the web server itself?</p>
