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.
