title: Visual Studio Team Services - builds have started to break after deployment
body: <p>We've been running an Azure VM doing CI behind Visual Studio Team Services (previously Visual Studio Online) for the longest time, and everything was working fine.</p>
  
  <p>Very recently, almost every build has started to break, /after/ the deployment was completed and during the last "Copy binaries" step</p>
  
  <blockquote>
    <p>Copy binaries to drop  Exception Message: The HTTP request timed out
    after 00:01:40. (type TimeoutException) Exception Stack Trace:    at

  <p>Any ideas as to what can be the issue?  The build server was rebooted and its drop folders cleaned up.</p>
