A few racks or even a couple of dozen racks could be called a datacenter, but nothing on any real scale. Enough to host important and niche things? Sure. I was referring more to like the size of what you might see in Quincy, WA.
Yes, but that's not where the volume is. A 'small' data center, even here in Europe has 100's of racks. There are of course many tiny ones but collectively they don't even add up to one single large Google or AWS DC. Those things will run in excess of 1 or even 2 GW.
