The distance to my workplace from my apartment is a bit over 4 miles. The distance between Tucson, where I am, and my parent’s house, is over 3,000 miles. So why is the average RTT of a network packet from my apartment to my parent’s computer 136 milliseconds, but 140 milliseconds to my work computer?
Well apparently the best route (as determined by the TCP routers involved) from my apartment to my workplace is from Tucson, to Dallas, to Los Angeles, to Phoenix, and back to Tucson. Sheesh.
