Digital Minefield

Why The Machines Are Winning

Unequal Internet Power


As our digital lives expand, we think less and less about how it all works. The more we use The Cloud, the less we concern ourselves with its details. Whether smart phone or computer, social media or Internet, we take too much for granted.

The digital universe is a complex amalgam of hardware and software, supported by millions of techies from electricians to systems designers. This post focuses on a tiny but essential piece of hardware we’re all using right this second.

You and this blog are connected to the Internet at different locations. At your end is a device similar to the one at the blog’s end. They’re called modems (for reasons no longer relevant).

Modems translate your Internet requests into tiny packets of information that travel (in non-trivial ways) across the world (or across town) to the specific modem linking the Internet to the information you’ve requested.

The modem at your end could be hiding inside your smart phone or sitting atop your computer. The modem at the other end, whether at this blog or somewhere in the bowels of the Google planetiod, is constantly talking to your modem over the Internet.

Your modem is only part of your Internet connection. In addition is your Internet Service Provider (ISP) with its hookups (cable, DSL, 4G). And your modem may have routers for Ethernet and WiFi. Whatever the combination, they all need power.

Some modems run on batteries and some have battery backup. A modem in a smart phone uses its battery. Google modems probably have their own electric company. Many other hundreds of millions of modems rely an AC plug in a wall socket.

These computers depend on the same power we used a hundred years ago. Better protected now, this power is still vulnerable to lightning strikes, terrorists, cars crashing into power poles (it happened here), solar flares, and other vagaries of the universe.

Power simply does not exist everywhere, at all times, and with perfect uniformity. But when it’s interrupted or raised (surges) or lowered (brownouts), it’s much more likely to be at your end than anywhere on the Internet or the big servers you access.

Are our digital lives ascending to the clouds or are we only falling further into the rabbit hole? Either way, when your power goes out you may be sitting in the dark, wondering where everyone went. They’re still there; it’s you who’s disappeared.
