Compromised batteries or battery controllers?

Witness A said, “It appears that the fire started when a spark flew during the process of replacing the uninterruptible power supply,” and added, “Firefighters are currently out there putting out the fire. I hope that this does not lead to any disruption to the national intelligence network, including the government’s 24 channel.”[1]

    How large is this UPS that a fire can bring down all 96 servers?

    This story is really unbelievable.

      I’m no expert but traditional lead acid battery UPS are typically at the bottom of the rack due to weight and concern about leakage. Wouldn’t surprise me if li-ion UPS go at the bottom as well. In that case if uncontrolled it seems pretty easy to torch an entire rack.

      96 servers isn’t that many, probably less than 10 racks and given the state of the backups it would track that they didn’t spring for halon.
