This issue driving me crazy! I have cron jobs that must run overnight
and
I started to see this pattern about 3-4 weeks ago. I had to run the
jobs multiple times and
I still have to check them every morning, because sometimes all of
them failed (with the same duration as you guys). Also,
I get this error at a 4-5% rate for client requests.

Google, please let us know what is going on.
