Abstract
Sometimes buildings just don't look as important as they are. This the case of One Wilshire Blvd in Los Angeles. At first glance, its a generic office building in downtown. But, that blank facade is hiding one of the most important pieces of digital infrastructure within the United States. In this video we visit 1 Wilshire Blvd, explain how it works, and chat with Jimenez Lai who wrote a story about the building which explores its outsized role in our digital lives.

The internet is the most technically complex system humanity has ever built. Jim Kurose, Professor at UMass Amherst, has been challenged to explain the internet to 5 different people; a child, a teen, a college student, a grad student, and an expert.

The technique selected for multiplexing was packetswitching. Au alternative such as circuit switching couldhave been considered, but the applications beingsupported, such as remote login, were naturally served bythe packet switching paradigm, and the networks whichwere to be integrated together in this project were packetswitching networks. So packet switching was acceptedas a fundamental component of the Internet architecture.
Packet-switched versus circuit-switched
The first networks were packet-switched over circuits. (I remember the 56Kbps circuit modems that were upgraded to T1 lines.) Of course, it has switched now—circuits are emulated over packet switched networks.

his environment of uncontrolled information is not all bliss, however. Some critics point out that the same giant media companies that dominated the older forms of media produce much of the content available on the internet.
Tada! And major companies also own most of the infrastructure on which the internet runs.

But that is changing.
who would've thought we'd cycle back to being at war and distance
as divisive as ever (?)
how technology is accused of bringing the faraway closer but distancing the nearby

to show how the design changes depending on the depth. The nearer to the surface you get, the more protection—armour—you need to withstand potential disturbances from shipping.
Hahaha! This is a bit counter-intuitive, is it not? One would think you would need ”bigger” cables as the depth increases, because of the pressure.

Have you ever thought about how that cat picture actually gets from a server in Oregon to your PC in London? We’re not simply talking about the wonders of TCP/IP or pervasive Wi-Fi hotspots, though those are vitally important as well. No, we’re talking about the big infrastructure: the huge submarine cables, the vast landing sites and data centres with their massively redundant power systems, and the elephantine, labyrinthine last-mile networks that actually hook billions of us to the Internet.
So, I take it we invested billions in the infrastructure, only to transfer cat photos from Oregon to London. Damn, I am really happy to be apart of the 21st Century!
BTW, did it occur to anyone we might be under the domination of Cat Overlords, since we are using such powerful infrastructure just to deal with photos of... cats? (pun intended)

Today the move to cloud computing is replicating some of that early rhetoric—except, of course, that companies now reject any analogy with utilities, since that might open up the possibility of a publicly run, publicly controlled infrastructure.
That's a distinct possibility - if the infrastructure could be built with trust. Keep hoping.
