Hi everyone. I'm stumped by something I'm seeing happen to my app on Google App Engine - tried asking on Stack Overflow with the App Engine tag but my question wasn't received well because it's not a programming question. I'd be very happy if anyone can shed some light on this though :)

I'm receiving a huge number of requests from IP addresses starting with 10. Afaik, this is a local IP. So, my question is why would Google's network be swarming my app with requests? It's costing me quite a few bucks in extra quota, so is cause for concern. I've attached the log I'm looking at. Thanks in advance if anyone has any idea what's going on!
