title: ELB health check behavior - Health Threshold
body: <p>In the dialog for setting up ELB health check it states:</p>
  
  <blockquote>
    <p>If an instance fails the health check, it is automatically removed
    from the load balancer. Customize the health check to meet your
    specific needs.</p>
  </blockquote>
  
  <p>I get that will remove the instance from behind the ELB when a health check fails. My question is around the "Healthy Threshold" setting. When you hover over the help there it says:</p>
  
  <blockquote>
    <p>Number of consecutive health check successes before declaring an EC2
    instance healthy.</p>
  </blockquote>
  
  <p>If the instance is declared healthy, is it pulled back into the load balancing group?</p>
