title: Azure Auto Scaling works but load doesn´t get distributed
body: <p>i have a problem with auto scaling in azure. The scaling process works fine but when a new instance is added it becomes no traffic.</p>
  
  <p>My scenario:</p>
  
  <p>I have 2 running instances whit a WCF webservice on it. Now i shot from 2 other servers(not azure) data to the webservice. 
  After a while the auto scaling kicks in and a new instance is added. The 2 servers are producing still load on the first 2 azure servers. However the new one doesn´t get any.</p>
  
  <p>I thought azure is using round robin for load balancing or am i missing sth. else?</p>
  
  <p>Thx for any help.</p>
