Previously we'd burn 4 minutes waiting for curl to bang its head
trying to get results which would never emerge. Change this so we don't
fail on a 404, and also pull the retry down quicker, so we'll spend a
maximum of 2 minutes waiting for a server to come back, and no minutes
when the results aren't there to be fetched.
