Personal bugbear: Ireland has a lot of connectivity but only three cables (two from Cork, 1 from the north-west) go to a destination other than the UK. All other Irish internet/telephony traffic goes through the UK. Remember that there are many European data centres and EMEA headquarters in Dublin.<p>Much of it goes through Bude in Cornwall, which has a GCHQ listening post perched over the submarine cable (<a href="https://en.wikipedia.org/wiki/GCHQ_Bude" rel="nofollow">https://en.wikipedia.org/wiki/GCHQ_Bude</a>). Or through Southport which is also known to be monitored by GCHQ.<p>I find it surprising, particularly as the UK prepares to leave the EU, that this issue isn't of more concern
Pretty interesting. I'd be cool to have one that showed the cables on land too. I wonder if there's a tool like that, be useful to plan where the best connectively is if you are building your own datacenter for example.
Here's Neal Stephenson's writeup on how the FLAG cable was laid: <a href="https://www.wired.com/1996/12/ffglass/" rel="nofollow">https://www.wired.com/1996/12/ffglass/</a><p>It clearly inspired some parts of Cryptonomicon.
This map is interesting too: <a href="https://www.us.ntt.net/about/network-map.cfm" rel="nofollow">https://www.us.ntt.net/about/network-map.cfm</a><p>It shows some overland links as well but it doesn't show intermediate hops. For example, you can see from other maps that most Pacific cables stop off in Hawaii.<p>You can match the nodes to entries in a trace root log. I did this for a chapter (on network latency and performance) in my last book.
I just found this one which has more details for the British Isles & Western Europe here:<p><a href="http://www.kis-orca.eu/map" rel="nofollow">http://www.kis-orca.eu/map</a><p>It also includes power map & wind turbines zones.
It's interesting how Russia only has two submarine cable connections, of which only one is international (with Japan).<p>Is it really so, or is data missing from the map? Anyone know the reason why?
Interesting summary of the process - <a href="http://thednetworks.com/2012/03/21/how-are-undersea-cables-laid-in-the-oceans-advantages-over-satellite" rel="nofollow">http://thednetworks.com/2012/03/21/how-are-undersea-cables-l...</a>
I first learned about the existence of this cables reading Arthur C. Clarke's <i>How the World Was One</i> (<a href="https://en.wikipedia.org/wiki/How_the_World_Was_One" rel="nofollow">https://en.wikipedia.org/wiki/How_the_World_Was_One</a>) which I highly recommend.
Much as this comment is like 40% trolling and likely to lose me what little karma I have, is there an easy way to see this data in a better projection?
