Some Facts About The Internet's Undersea Cables by MRAKBEE(m): 8:07am On Aug 11, 2017
The Internet is really just a spaghetti-work of really long wires. But what we see is just a small part of the physical makeup of the net. The rest of it can be found in the coldest depths of the ocean.Ninety-nine percent of international data is transmitted by wires at the bottom of the ocean called submarine communications cables. In total, they are
hundreds of thousands of miles long and can be as deep as Everest Is tall.
Here are some things you might not know about the Internet’s system of undersea cables.

1. CABLE INSTALLATION IS SLOW, TEDIOUS, EXPENSIVE WORK.
The cables are installed by special boats called cable-layers. It’s more than a matter of dropping wires with anvils attached to them—the cables must generally be run across flat surfaces of the ocean floor, and care is taken to avoid coral reefs, sunken ships, fish beds, and other ecological habitats and general obstructions.
The size difference is related to simple vulnerability—there’s not much going on 8000 feet below sea level; consequently, there’s less need for galvanized shielding wire.

2. SHARKS ARE TRYING TO EAT THE INTERNET.
There’s disagreement as to why, exactly, sharks like
gnawing on submarine communications cables. Maybe it has something to do with electromagnetic fields. Maybe they’re just curious. Maybe they’re trying to disrupt our communications infrastructure before mounting a land-based assault. (My theory.) The point remains that sharks are chewing on the Internet, and sometimes damage it. In response, companies such as Google are shielding their cables in shark-proof wire wrappers.

3. THE INTERNET IS AS VULNERABLE UNDERWATER AS IT IS UNDERGROUND.
While the ocean is free of construction equipment that might otherwise combine to form
Devastator, there are many ongoing aquatic threats to the submarine cables. Sharks aside, the Internet is ever at risk of being disrupted by
boat anchors, trawling by fishing vessels, and
natural disasters. A Toronto-based company has proposed running a cable through the Arctic that connects Tokyo and London. This was previously considered impossible, but climate change and the melting ice caps have moved the proposal firmly into the
doable-but-really-expensive category.

4. SUBMARINE COMMUNICATIONS CABLES ARE FASTER AND CHEAPER THAN SATELLITES. CHEAPER THAN SATELLITES.
Though fiber optic cables and communications satellites were
both developed in the 1960s, satellites have a two-fold problem: latency and bit loss. Sending and receiving signals to and from space takes time. Meanwhile, researchers have developed optical fibers that can transmit information at
99.7 percent the speed of light. For an idea of what the Internet would be like without undersea cables, visit Antarctica, the only continent without a physical connection to the net. The continent relies on satellites, and
bandwidth is at a premium.

5. FORGET CYBER-WARFARE—TO REALLY CRIPPLE THE INTERNET, YOU NEED SCUBA GEAR AND A PAIRE OF WIRE CUTTERS.
The good news is that it’s hard to cut through a submarine communications cable, if only because of the thousands of very lethal volts running through each of them. The bad news is that it is possible, as seen in Egypt in 2013. There, just north of Alexandria, men in wetsuits were apprehended having intentionally cut through the South-East-Asia-Middle-East-West-Europe 4 cable, which runs 12,500 miles and connects three continents. Internet speeds in Egypt were crippled by 60 percent until the line could be repaired.

Numerous wonders in this world. Internet is seemingly the second god. It sustains and controls its mortal creators. It is the brain of the world.

Yeah.. The Internet controls almost every aspect of our lives that a breakdown spells doom for us all
