DeadlineExceededErrors with GAE/Google API refresh

Question

Over the last few days I have been encountering DeadlineExceededErrors in my GAE app that interacts with the Google Calendar API. As far as I know these errors have been sporadic; I was not given these errors last night, but was during yesterday during the day and now this morning. I am not getting these errors when I run on the local dev environment, which makes me wonder what is going on with the GAE servers to cause this issue and how I can fix it.

I tried setting my urlFetch deadline to 45-60 but it didn't make a difference. I also tried building an HTTP object with a high timeout, but it didn't matter. The log looks like this:

2013-06-07 11:21:06.079 make: Got type <class 'google.appengine.api.datastore_types.Blob'>

E 2013-06-07 11:21:15.989 Deadline exceeded while waiting for HTTP response from URL: https://accounts.google.com/o/oauth2/token Traceback (most recent call last): File "/py

Why is it choking on the refresh process now?

Edit: I should add that my app interacts with the Facebook API as well and I am not receiving DEEs for that.
