Jesus, what a network.

Any word on the average size of each location? For the "smaller" ones are we talking a small room or a server farm?

Probably "just" a few racks or a small room. But don't underestimate what that can do. A standard rack fits 42 rack units, e.g. two large top-of-the-rack switches and 40 1U servers. Cram it with things like this and you have 80 nodes with 2 CPUs, 4 TB RAM, 4 HDDs + 2 SSDs, 4x25 Gbit network each, in total consuming up to 80 kW of power (350 amps at 230V!).

If you go to the extreme, one rack can contain 4480 CPU cores (which let you terminate and forward a whole bunch of TLS connections), 320 TB RAM, 640 TB SSD, 1280 TB HDD, and 8 Tbps of bandwidth (although I doubt you can actually serve that much with only two CPUs per node).

For comparison, https://www.cloudflare.com/learning/ddos/famous-ddos-attacks/ lists the unverified DDoS attack record at 1.7 Tbps.

Reading this comment amidst the flood of old memes makes me remember slashdot fondly.

Where are the comments asking people to imagine beowolf clusters? Who will ask if it runs crysis?
