I worked in a DC that had multiple redundant chillers on the roof, and multiple redundant coolers on each floor, but the whole building's cooling failed at once when the water lines failed somehow.
They didn't say how, but apparently the pipes between each floor and the roof were not redundant. It took almost 24 hours to fix.
