Rather unlikely - for one, none of our other devices connected in that
data center are experiencing any problems, most of which do come with a
certain degree of power monitoring (two ASR1001, 3825, 2x 2960S multiple
servers with management cards, etc.) - plus, on a general input power
problem, I would assume all power levels would dip, not just single
feeds ... especially with massive dips I've seen in the env history
(nominal 3V, measured <1V, etc.)
I also assume the DC management has a close eye and monitoring hardware
to ensure their power levels are correct ;)
