Here’s how the Internet’s arteries travel across the world's oceans in 2014

Interactive version of the 2014 submarine cable map.
TeleGeography’s Submarine Cable Map has been updated for 2014, 
providing an excellent representation of the infrastructure that makes global connectivity global.
The latest edition depicts 285 cable systems that are currently active or due to enter service by 2015.

Great news for connectivity connoisseurs: the analyst firm TeleGeography just published this year’s edition of its world map, featuring all the submarine cable systems that comprise the arteries of the internet.

The map also shows the cables’ landing points, which is handy for those who take an interest in the current surveillance scandal.
Why is British intelligence so good at tapping cables?
Here’s why – so many of them pass through the U.K.:

The 2014 edition includes 263 cables that are lit (in service), and 22 that should be lit by the end of 2015, so 285 cable systems in total.
Last year’s map showed 244 cables, and the year before that just 150, so the cable-laying boom of a few years back has definitely slowed down.

Unfortunately this year’s edition lacks a neat feature of Telegeography’s 2012 and 2013 maps, which was a breakdown of how much of the cable systems’ capacity is actually being used.
It also doesn’t have the 2013 edition’s Olde Worlde appeal.
On the plus side, it does offer a good breakdown of cable faults over recent years, cable-laying ships and maintenance zones, if that’s your thing.

One cable system that’s not on the map, probably because it will only go live in 2016, is the Asia Africa Europe-1 (AAE-1) cable that was detailed on Tuesday.
AAE-1 will run from South-East Asia to Africa and Europe via the Middle East, and yesterday the backing consortium announced membership including the likes of China Unicom, PCCW, Etisalat and Ooredoo.

Main projection

The map depicts routes of 263 in-service and 22 planned undersea cables.
Each country is colored according to how many international submarine cable system links are connected there.
Capital cities and the location and direction of 44 cable vessels (as of December 6, 2013) are also provided.


Cable landing sites

The map provides detailed information about cable landing stations in key regions including Hawaii,Southern Florida, New York, New Jersey, Cornwall, Singapore, Hong Kong, Tokyo, and Sydney.

Inset map

An inset map presents geographically accurate submarine cable paths, the locations of seven cable maintenance agreement zones, and subsea topographical features.


Cable installation

The map includes a diagram highlighting the various parts of a submarine cable system, including a submarine cable cross section.

Cable faults

Infographics provide data on cable faults and repairs, including:
  • Causes of cable faults, 2008-2011
  • Number of cable breaks by country, 2008-2012
  • Mean time to commence repair by country, 2008-2012

Seabed profiles

The map provides examples of trans-Atlantic and trans-Pacific cable route seabed profiles.
