I think the problem is that we're not doing a good enough job on our Instances console. You do have three always-on instances, that were initialized with a /_ah/warmup request, but we don't give you an indication of how old they are. I do see /_ah/warmup requests in your logs on 12/14 and 12/12. So, you had three always-on instances that remained up for two days. You can check the Instances console at any time to see how many always-on instances and dynamic instances are currently running for your app.
Your app is a bit more interesting in that it will occasionally need more instances to handle traffic. For example, right now you have three always-on instances and one dynamic instance. The dynamic instance may be turned up be either a loading request or a warmup request, in the same way that a always-on instance might be turned up by one or the other. We try to turnup with a warming request but don't guarantee it right now.
