Like many larger corporate and colocation data centers, there is an explicit policy forbidding the installation of a UPS in any rack -- the DC itself has multiple large-scale UPS systems and a gigantic diesel standby generator. While this does provide cleaner power than the municipal feed, glitches still happen. Most of the other machines in the same cabinet as the haunted nameserver have dual supplies. I've been told that part of the justification for the "no UPSes" rule is so that when the "big red button" is pushed first responders can have faith that all circuits are dark. Policy, fire code, and corporate politics get in the way of perfect uptime records, but if this rule saves my peers from electrocution, I'm not going to argue against it. Kevin
