Demand and Supply
The first undersea cable was laid in 1850, under the English Channel between Dover and Calais. It consisted of copper wire waterproofed by a layer of hard, inelastic rubber made from gutta-percha trees. Lead weights were attached to keep it on the seafloor. The cable carried telegraphs for three days—until French fishermen accidentally cut it.
Modern fiber-optic cables are more reliable and numerous. Today, between 250 and 300 cables beneath the ocean floor are active at any given moment. And as demand for bandwidth grows (international traffic increased 53 percent between mid-2007 and mid-2008, according to research firm TeleGeography), more and more are needed.
Some of the cables Rennie spends his days fixing reach land near Miami. Here, the cables are bundled and shunted along under the old Florida East Coast Railway that ran from Miami to Key West until 1935, when Hurricane Islamorada wiped it out. The East Coast line was known as the "overseas railroad" because of all the bridges and viaducts it had to cross to reach Key West. Now it is the preferred track for the undersea cables that surface in central Miami, home to Terremark, one of the most important telecom firms you've never heard of.
Terremark's six-story, 750,000- square-foot headquarters has no windows. They're unnecessary, since the main occupants of the building are computers: server racks owned by the likes of Deutsche Telekom, Facebook and the U.S. Department of Defense, not to mention the Internet Corporation for Assigned Names and Numbers, the organization that issues domain names, and VeriSign, which provides the infrastructure for secure online financial transactions.
On the 'World Map' in the 'How the traffic flows' display, why is there no mention of bandwidth in/out of Russia?
Being cut off from customer service in India no I would not be bothered by that at all.
I think it might have been better if they left those lines broken and pulled up all the cable.
I found the articles on the Internet and the Inkjet printers fascinating; two things that we use daily; sometimes when I see the cover of the magazine I believe it should be called PopSciFi, I understand that you need to capture peoples attention but there is plenty of wonderful things already in use that people do not know how they work, I will give you an example: my inexpensive watch that is synchronized daily with the atomic clock (Is that wonderful or what?).

Marustkl, I hope I spelled your UN correctly? Small "l's" and "i's" play games with my vision.
So odd when I decided to turn on my PC, go to Pop Sci, and find pages 50-1. My actions for doing so were, (1) could not find Australia and, (2) no Russia either.
Of course page 1 on the NET brought me to your question first. That was when I noticed "Sydney," but still no Russia. Strange!
You would think there would be some interesting views and info with Russia, Alasaka, and the Bering Strait!
Of course in my interest to comment after seeing yours', I logged right in and typed this without finishing the article, Yet! I hope I'm not eating shoe in a few minutes, I very seldom comment on anything and I'm still wondering if I'll learn from my hasten urges, or go back to my "NO"= opinion/comment/question attitude?
Your caption is wrong, Dorset is a county, not a port.
just wanna say great article! i had no idea the internet was that hard-wired around the globe.
to stop terrorists from disrupting the internet by destroying the cables wouldn't it make sense to have all the cables linked so they would destroy their own internet capability
Your article was very interesting and informative; but as I read the article; I couldnt help but wonder if you are giving future terrorists another avenue in which to disrupt the world.
very usefull article.
who protect internet? we all must keep the internet
I hope you will permanently abandoned the notion of ever going back. You made me smile.

I wonder if cookie-cutter sharks can also disrupt these cables as well. I have heard they can reek havoc on power cables (they cut out the insulation).
Your actulally quite right. The internet is a collection of networks not necissarily IP based. A majority of attacks exist on the IP side. Wide area networking technology carries all traffic regaurdless of the payload. If there is an attack on the border of your internal IP network the WAN cares not. If your border is penatrated and a connection is made to create another network, again the WAN doesn't care. Can the internet be taken down? Not if you have skilled and knowledgeable Information Security officers maintaining the network you reside on.
If there is an attack on the border of your internal IP network the WAN cares not. If your border is penatrated and a connection is made to create another network, One latest thing for all of you guys, their a campaign started by a university here is a link of it. kindly check it its really useful i think.
The map on the 2nd page is not correct. Where's Russia and Eastern Europe?

A big thanks to engineers like John Rennie who work round the clock to ensure that we continue to have the internet connectivity that we most depend on for our 24 X 7 online global communication. I didn't even realize that it is the undersea cables, that carry phone and Web traffic from continent to continent at the speed of light, which made this possible. Full marks to James Geary for providing this mind boggling revelation.

Really, I believe the search engines are solely responsible for protecting innocent children and other dangerous aspects of the Internet. They use an algorithm that keeps the quality sites on the top 10, while keep the dangerous, pornographic, violate, adultery information at a minimum, unless of course you search it up, while kids won't do most likely at a YOUNG age.
I never really thought about how the internet was linked around the world... this was very informative and eye opening.

Its a tough job, but someone has to do it!
When will satellites eliminate this cabling need running around the world? It seems like this hard wire could be a good backup for the future to satellite transmissions. Just a thought...?
I wanted to know more of the internet linking, and this article was very very interesting for me ...
It's interesting to be reminded of the actual physical underpinnings of the internet from time-to-time. As much as we focus on what is virtual, whether shopping, dating, news, etc. there is always something and someone in the real world keeping the plates spinning.
Thanks for the interesting article.
It’s frightening how much we have all become reliant on the internet for communication, trade and our general safety. I dread to think what would happen if a natural disaster destroyed the cables beneath the North Sea; it would have a knock on effect of tremendous damage to the western world. I hope there are plans for a backup system as we have already seen the disruption a few damaged cables can cause next time we might not be so lucky.
Very though provoking article.
It is great that they use remotely operated submarine deep to repair underseas cables which are vital in connecting continents across the vast oceans. The article shows how interconnected we are and why the wrong cut in the cables could greatly impact one or more countries.

great article. Most people would be surprised to see the size of the cables connecting continents.

Good thing, otherwise i couldn't access
