Submarine cables at #euroix #ixp

Good talk at Euro-IX on submarine cables from Alan Mauldin of TeleGeography.

The world is still very much increasing it submarine cable capacity. Interestingly the drivers for new builds are not capacity exhaustion. It’s more likely to be down to a range of things including Route Diversity – new physical paths being valued, Cost Optimization – use of new technology may lead to long-term unit cost reductions, Competition — still room for new competitors in some markets where high prices persist, Build-vs-Buy Strategy – become an owner, not buyer, of capacity, Peer pressure, ego, national, & corporate pride and First cables (for some island nations).

I quite liked the national/corporate pride bit. It follows on from a chat I was having on the subject of size pipes during the break. In our internet world the capacity of your network connection(s) is a bragging point.

Chat up line of an internet geek: “Fancy coming back to my place to see the size of my pipe?

Timico customers are taking 10Gbps connections. I’m looking forward to our first 100Gbps connection.undersea cable capacity

I lifted this chart from Alan’s presentation (thanks Al). It shows that we, the world, currently have roughly 70Terabits per second of intercontinental internet capacity. Impressive. We aren’t using it all yet of course but the only way is up.

Interactive submarine cable map here. I think I may have linked to this before but no harm in doing it again.

Another interesting interactive map is of the world’s internet exchanges here. This shows you where the meeting points of the internet are. The places that ISPs connect to/at to carry your internet traffic. When you send an email or click on a web page the data will travel through one or more of these places.

It doesn’t cover private connections but these will largely be done at the same locations. That’s all.
