"All of the fiber-optic cables buried in the sea bed are logged by Washington research firm Telegeography in an interactive Submarine Cable Map. The company's research director Alan Mauldin told CNN about the world's underwater networks."
From the interview:
for international communications, over 99% is delivered by undersea cables.
75% of faults are due to external aggression the majority through human activity such as fishing, and ship's anchors.
There are about 13 cables in service across the Atlantic, and less than 20% of potential capacity is what we call "lit" or in service right now.
cables are designed to last for a minimum 25 years.
Once you build a cable the cost of buying capacity incrementally over time is very affordable.
The last cable across the Pacific cost $300 million; one cable that entered service last year in Asia reaching many locations cost $400 million
The UK's most senior military officer has warned of a new threat posed by Russia to communications and internet cables that run under the sea. Air Chief Marshal Sir Stuart Peach, the chief of the defence staff, said Britain and Nato needed to prioritise protecting the lines of communication. He said it would be an "immediately and potentially catastrophic" hit to the economy if they were cut or disrupted.
The cables criss-cross the seabed, connecting up countries and continents. [...] Speaking to the Royal United Services Institute defence think tank, Sir Stuart said the vulnerability of undersea lines posed a "new risk to our way of life".
