One of our power distribution units in Reynolds House has restarted several times, including de-powering and re-powering connected devices several times. Some customers whose equipment was powered from a single feed will have lost power.

    The PDU continues to show random power outlets as down each time we query its status. While we do not believe that it is actually power-cycling those ports, we do not trust it to continue behaving and so have moved all single-powered devices off that PDU and onto the other PDU in that rack.
