Yes, we have been having intermittent URLfetch errors for months now. It seems like a DNS issue, as the urls are fetchable from dev server or directly. The first post, Google said they found an upstream provider that was giving a DNS error. Subsequent posts have gone unanswered.
We space the fetches out, so as not to spin up any extra instances,so I doubt it is a throttling issue. It seems to me that Google has an intermittent problem somewhere connecting to the internet.
