#42Poor New Zealand!
More like poor Cuba!
Linked by ALBA-1[0], which apparently is carrying public traffic since early last year[1], although everything in Cuba is highly restricted and filtered by the state. Worth reading the Wiki article[2]

#43Totally awesome. But can't buy the wall map until they fix the "asterix" typo!
Re: Submarine Cable Map 2014
#44I'm curious how many of them are tapped? Or would need to be tapped to get total coverage?

#45Earlier quoted context omitted.
I live in southeast AK. An earthquake near Glacier Bay this month broke one of the undersea cables, which caused an outage for customers of one service provider. I had no idea there were multiple cables to southeast, until I read about the response to this incident. The Capital City Weekly has a good article about the recent incident, which also includes a short history of communication cables in Alaska [0]. Basicall…
I wonder why they didn't just lay them along the alcan highway? Surely that would have been a zillion times cheaper.
http://gregorio.stanford.edu/holbrook/CableCosts.html says that cost of undersea cables in the '90s was in the $27k-$56k/km range, with the $27k a bit of an outlier.
Cost estimates for terrestrial cable are harder to come by, and seem depend a lot on things like rights of way (likely not relevant here as a cost), terrain (_very_ relevant), ability to get equipment to the right location, etc. But the numbers I'm seeing on various links from https://www.google.com/search?q=cost+of+laying+fiber+optic+c... are in the $20k to $40k range per kilometer (I took the actual numbers I saw and divided by 1.6) about 5-10 years ago. Figure about 1.4x smaller if you want to adjust for inflation to compare to '90s numbers.
All of which is to say that "zillion" in this case is probably a number somewhere between 1 and 4. Give or take; these are all estimates, obviously. Also not clear to me which is faster to lay, by the way, which might matter in terms of deciding which one to do.
Not to mention that the undersea cable might be shorter, offsetting some of the per-km difference in cost, since it's a lot easier to go straight.

#46How do they handle it when cables cross over each other and they need to do repair on the one on the bottom?

#47anyone have any idea what happens to user experience when one of these guys breaks? is it a big deal? what about islands who are surviving off of one cable connection?

The map notes a "resiliency" factor for each country. A country with a single link has very low resiliency. Most likely a lot of people lose their connection while higher paying customers/more important data gets routed to satellite communication systems.

It's a bb play. They're not looking to sell to consumers, they sell to companies that need this map for reference.

#50What sort of tech is it built on? Looks like Mapbox.js plus probably designed in TileMill, then self-hosted? What else went into making it?
