To be fair, the polls were consistently in the opposite direction. 538 had clinton at 70%, PEC at 99%, everyone else somewhere in between. It's a black swan event, bubble or no.
A 30% probability event coming to pass isn't a black swan event. This term is unfortunately overused for anything unexpected but that isn't what it means.
LA times had it for trump. They had their own weighting. Their results when adjusted for commonly accepted weighting matched the common poll average. So it is in the weighting.
