DeadlineExceededErrors with GAE/Google API refreshing access token
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:

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.
I think it may have been due to this issue?
