title: Azure Service fabric - upgrade takes very long
body: <p>I have a SF app and the build server pushes out an upgrade. Usually this takes about 15 mins or so but recently the times have been going up</p>
  
  <p>Somewhere around #78 we switched to a new cluster - but it's the same config and same region (5 A1 servers).</p>
  
  <p>For the latest one where it's been upgrading for more than an hour, on the fabric explorer, still the first node is being upgraded and couple of services have 1 unhealthy partition.</p>
  
  <p>Any help/tips on how to get this to behave a little more consistently?</p>
