Sune Christesen's data center map http://bit.ly/tYnlD layers nearly 2,000 locations on top of Google maps, complete with information on which carriers serve each one, etc.  Besides being a practical tool, it provides another way to look at the concentration of the Internet. The left picture shows a heavy concentration in Britain, Benelux and Southern Germany. That's no surprise, with the London and Amsterdam Internet exchanges being among the busiest in the world. The picture on the right is lower Manhattan and nearby New Jersey, probably still a busier switching point than London but I haven't seen any solid data lately. Until recently, African capital cities 100 miles apart connected through New York or London. In downtown Manhattan, there were big colocation cages and fat pipes from China Telecom and nearly every other major carrier.9/11 threatened the heart of the Internet. Ne w York is an efficient locus for government agencies.
That's changed over time, so I glanced at Sune's map of Asia as well. He only has 2 sites in Japan and 10 in China, which I'm sure is a matter of the Asians not providing him the information. Listings are free, so I expect more will come as word gets out. Thanks to James Enck's always useful EuroTelcoblog for the pointer.
