The Men Who Fix the Internet
An anonymous reader writes "Remember all those undersea cables breaking? PopSci.com introduces John Rennie, who '... has braved the towering waves of the North Atlantic Ocean to keep your e-mail coming to you. As chief submersible engineer aboard the Wave Sentinel, part of the fleet operated by UK-based undersea installation and maintenance firm Global Marine Systems, Rennie — a congenial, 6'4", 57-year-old Scotsman — patrols the seas, dispatching a remotely operated submarine deep below the surface to repair undersea cables.' The article goes on to outline the physical infrastructure of the Internet, including some of its points of vulnerability."
Grounds keeper Willie of the undersea cables, at your service.

While there is loads of critical data that goes through these cables, I feel bad when these guys are working their asses off to make sure that 4chan or youtubes of a chimpanzee riding on a segway gets to its proper place.
Dragging an anchor isn't something you try to do. It's something that happens when the weather is more then the anchor can handle. Better to drag the anchor then to rip the anchor capstan off the boat. Funny how boats and cables both anchor near the shore ... you know, that place where people are.
You anchor down if it's stormy and you can't escape it. With strong currents or wind you might end up dragging the anchor. That's the only explanation I have.
There are enough satellites up there that we can get *some* communications without cables. Those satellite links suck at the best of times, though - if nothing else they have horrible latency, and can't approach the huge bandwidth of an undersea cable full of optic fibres. Just like in your own apartment, wireless is cool for convenience and for when you have a kitten (or fishing trawler) messing with your wiring, but cabling is always faster and better for fixed installations.
Rampant carbon sequestration destroyed the Dinosaurs' tropical paradise. I'm here to help repair the damage.
This is yet another example of the jobs which we rely on everyday but don't give much thought to. Also, this make me really think there is a great job out there to fit everyone. (When the economy improves that is.)

Holy crap! The Internet *is* a series of tubes! Evidence:Image from TFA
Did you never waatch Pirates of the Carribean? I seem to remember the equivalient of a hand-brake turn using anchor.
Perhaps they used an internet cable to stop
You anchor down if it's stormy and you can't escape it.
That's pretty much it. The last thing a skipper enjoys is to be pinned against a lee shore by a gale. If he can't get into the safety of deep water, dropping the hook is sometimes the only option. Sometimes, if his hook is too small or if its chain is too short for the wind/current load, it'll drag. It's not a fun situation to be in; I've been there.
Everytime we have a connectivity hiccup I am flooded with calls from our users asking "Is the Internet broken?"
It takes everything in my power not to say "Yes. The Internet is, in fact, broken"
Don't be so harsh. In English it's "preventative" maintenance. I would guess in US English it's "preventive" (I didn't know that, so thanks)
From TFA:
"If terrorists managed to gain remote access to a facility's command-and-control system, they could, for example, cause the generators to overheat and explode."
If you can make a generator explode on command, you really are doing it wrong. Backup generators may be able to be remotely started, stopped, switched in/out and checked but you should not be able to do the equivalent of burnouts with them.
Additionally, the article states that catastrophic failures would start to creep in after ~2 days of no human maintenance. WTF? Most exchanges and data centres I've been in are ghost ships 350 days a year aside from upgrades and config changes, how is it that such critical hardware can't tick over by itself for a month or so without going nipples skyward?
Hell, the average telephone exchange, if you nuked everything around it, would be giving dialtone and DSL to the skeletons for at least a week, probably more depending on how much diesel is in the tanks.
There is no music - home taping killed it.
