Because it’s faster if you have to climb down off a ladder first before pulling up the floor tiles to track down the roll of tape?
Oh, you mean that’s the single best reason for overhead COOLING. :P
The tiles intended for cold air flow have lots of little 1/4" or so holes in them that a roll of tape can't fall through. The roll of tape *can* escape through the 6x6 cable cutout under the rack if there aren't too many cables in the way. If we had overhead cabling and under-floor cooling, we'd have no large cutouts anyplace. :) (Alas, the data center across the hall is 27 years old, and we'll need to build a new one to fix it. Someday soon, maybe. :)
