Outbound bandwidth is consumed by either (1) the application serving data
in response to incoming HTTP requests or (2) the application initiating an
outbound request (urlfetch, sockets, etc). In the first instance, you
should see incoming requests in the Logs section of the App Engine console.
Make sure you look at every log and every part of the logging page; you
have to use the dropdown box to view the logs of different modules and
backends. In the second case (outbound requests such as urlfetch) you
should audit your code and attached libraries to figure out where outbound
requests are originating from. If you can't find the source, use AppStats (
https://developers.google.com/appengine/docs/java/tools/appstats ) - it'll
show you when and where outbound requests are coming from.
