The informational builders keep failing since 7am-ish 05/24/2017 with the message below. There was maintenance, but supposedly the outage is over now?

 If the buildbucket_id to insert is duplicated to the buildbucket_id of an old build and the old build was canceled because of a waterfall master restart, please ignore this error. Else, the error needs more investigation. More context:  crbug.com/679974  and  crbug.com/685889
