How come some of the Washington and San Jose hops only list one packet latency value... that means the packet didn't get back to me, right? Update: I learned from Stefan at BOSCO that until the undersea cable recently installed in Kenya is carrying Ugandan packet data, Uganda still gets all of its Internet from a satellite connection. At the MTN/AppLab offices in Kampala, there are 2 really huge satellite dishes that, I bet, carry a lot of this traffic. I am not sure how satellite hops work, but if you take a look at the traceroute below, you can see that somewhere around hop 8, 9, and 10 Ugandan Internet traffic goes up into Outer Space... and then back down to Europe!
