As you mentioned, your App Engine resource usage is a combination of all of your services and versions. Mainly your 'api' and 'cron-backend' services, as they have the most instance usage due to URLFetch requests and Datastore/Memcahce interactions. Your 'api' service also saw a spike in errors which could have caused all of those failed requests to retry multiple times, causing an increase in networking usage.
As previously recommended, you should work with the billing team to confirm your specific case, and ensure that other versions of services have been stopped to reduce instance hours, and that errors are fixed to prevent spikes in retry traffic resulting in excess instances and network usage. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
