title: Azure websites auto scaling - unable to scale resource
body: <p>I have a website deployed into azure using azure websites. It has been running fine but for the last 2 days the autoscaling has been giving me the following error:</p>
  
  <p>The autoscale engine unable to scale resource '/subscriptions/guidhere/resourceGroups/Default-Web-WestEurope/providers/microsoft.web/serverFarms/Default1' from 2 instances count to 3 instances count.</p>
  
  <p>My site ie deployed with a minimum of 2 instances and increases to 3 if the CPU is greater than > 60 for a period of 15 mins. </p>
  
  <p>This auto scaling has been working (I have checked the web hosting plans logs) and it has managed to increase from 2 to 3 instances and down to 2 again satisfactorily but for the last 2 days it has shows a buch of errors in the logs saying "The autoscale engine unable to scale resource ... from 2 instances count to 3 instances count".</p>
  
  <p>Over the last 2 days, it has attempted to scale up about 20 times(it retries after 15/20 minutes after the last failed attempt). Out of these 20 or so times, it has failed about 17 and succeeded about 3. On a "normal" day, it scales up without any issues....</p>
  
  <p>Can anyone shed anylight on this? Is this a problem with azure? Is there something I can do?</p>
  
  <p>All help appreciated.</p>
