title: load balancer won't remove itself from dns
body: <p>I switched to autoscaling today and I created a new load balancer to practice with.  Once I got everything configured the way I liked it, I changed the A record to point to the new load balancer alias.</p>
  
  <p>Then the weirdness begins...</p>
  
  <p>My traffic has now split between the two load balancers.</p>
  
  <p>Here's some stuff that may help:</p>
  
  <pre><code>elb-describe-lbs
  ...snip
  LOAD_BALANCER  lb-app           lb-app-2007138663.us-west-2.elb.amazonaws.com          2012-12-01T04:36:44.480Z  internet-facing
  LOAD_BALANCER  app-lb-west      app-lb-west-650828891.us-west-2.elb.amazonaws.com      2013-06-28T01:34:26.810Z  internet-facing
  </code></pre>
  
  <p>I added <code>app-lb-west</code> and then switched the alis from <code>lb-app</code> to <code>app-lb-west</code>.  Now I'm getting 1/2 the traffic spread between the two lbs.</p>
  
  <p>I could use some help, please.</p>
