Maps of submarine cables

Hello, the recent news coverage of cuts to submarine cables and the impacts
this has on the Internet highlights why the geography of cyberspace matters
in a very material sense.

Les Cottrell has done a useful bit of quantitative analysis of the recent
events in a online paper, "Effects of Fibre Outage through Mediterranean".

This links to a nice overview map of submarine cables produced by the
Guardian newspaper (using TeleGeography data). The TeleGeography
Research cable map poster can be seen purchased.

Other sources of global-scale submarine cable maps include:

- Alcatel-Lucent, (2007 version)

- An older 2006 Alcatel version

- And an even older 1999 that I had archived

- KDDI's 'Global Network Map'
- Tata Communications' 'Global Footprint Map'
- PCCW Global 'Cable Map' (29 meg pdf!)

If people know of other good maps please let me know.

It is also interesting to compare the current geographic structure of cables
to telegraph routes from an earlier era of global telecommunications.
