GAE app went over quota "Incoming Bandwidth" after serving only 3 requests
===

I have a low traffic site at https://paperlink2.appspot.com

I enabled the billing over the weekend to tweak the datastore. When it was done, I disabled the billing.

Yesterday, just after the midnight, I notice my "Incoming Bandwidth" was over quota.

Since the over quota happened right at the midnight, I paid close attention today - and it went off after serving only 3 requests... 9 kb... in 3 minutes...

How could that happen?
If anyone in the GAE team could have a quick look, I really appreciate~~
Could anyone please give any suggestion? Thanks!

    This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.
