title: List remote refs failed: java.net.ConnectException: Connection time out: github.com
body: <p>I've recently starting seeing the above error with ever-increasing frequency on our build server. Nothing has changed in our TeamCity configuration during this period, so I'm guessing it might be changes at GitHub that are causing the error.</p>
  
  <p>I've tried changing our VCS polling interval from 60s down to 600s in case GitHub was doing some kind of connection throttling, but there has been no affect.</p>
  
  <p>Is it possible to make TeamCity less sensitive to connection timeouts?</p>
