Longitudinal View

A representation of the internet by longitude, from the Cooperative Association for Internet Data Analysis.

From CAIDA's site:

This visualization represents a macroscopic snapshot of the Internet for two weeks: August 1st, 2007 through August 15th, 2007. The graph reflects 760,922 IP addresses and 1,400,796 IP links ... We aggregate this view of the network into a topology of Autonomous Systems (ASes), each of which approximately maps to an Internet Service Provider (ISP). We map each IP address to the AS responsible for routing it, i.e., the origin (end-of-path) AS for the best match IP prefix of this address observed in Border Gateway Protocol (BGP) routing tables. Eighty percent of ASes with known locations are placed in the Americas, Europe/Africa, and Asia/Oceana.
