Cyber War!

the spread of slammer
The Slammer worm (also known as the Sapphire worm) was the fastest worm in history -- it doubled in size every 8.5 seconds at its peak. From the time it began to infect hosts (around 05:30 UTC) on Saturday, Jan. 25, 2003, it managed to infect more than 90 percent of the vulnerable hosts within 10 minutes using a well known vulnerability in Microsoft's SQL Server. Slammer eventually infected more than 75,000 hosts, flooded networks all over the world, caused disruptions to financial institutions, ATMs, and even an election in Canada. Here's a map that shows how quickly the worm spread over the first half-hour of tracking (Macromedia Flash required).
major u.s. internet routing sites
The Internet (formerly ARPAnet) grew from a defense and research institution-based network to a mass of interconnected nodes that are spread all over the U.S. Many different providers have networks that span the country (and, for that matter, the globe) but in order for the system to function effectively these various networks must be connected at some point. Here is a map showing the general layout of networks in the U.S. and the "peering points" (i.e. the points at which networks are connected to each other).
