Sometimes it takes more than the default 5 seconds for a remote API call to complete, and I think that we need to accept that. The solution is to increase the timeout period.
I have been using the following workaround to increase the timeout. Just add this snippet above the rest of the import statements. # Fix for DeadlineExceededError # Increase the amount of time before an API call times out # Original code from https://groups.google.com/forum/#!msg/google-appengine/OANTefJvn0A/uRKKHnCKr7QJ from google.appengine.api import urlfetch real_fetch = urlfetch.fetch def fetch_with_deadline(url, *args, **argv): argv['deadline'] = settings.URL_FETCH_TIMEOUT logservice.flush() return real_fetch(url, *args, **argv) urlfetch.fetch = fetch_with_deadline I use a value of 10 for settings.URL_FETCH_TIMEOUT (double the default of 5 seconds). Since adding this code, I have reduced the number of DeadlineExceededErrors from several per day to just one every few months.
