Hi, I've been thinking about the physical distribution of Tor nodes around the world. I wrote a really simple parser that does geo-ip lookups of public servers and plots them on a map.
If you're interested in seeing almost all of the Tor servers on a global map, check it out here: http://crypto.nsa.org/maps/tormap.html As an extra effort just because it's a small dataset, I also tried to map all of the mixmaster servers: http://crypto.nsa.org/maps/mixmastermap.html If anyone has any interest in this, I'll probably automate it and put it up somewhere else. Best, Jacob
