Interesting! Had a jolly time trying to initially figure out what was going to happen across the world specifically between Feb 16-19 and Nov 10-12, 2009, as well as what is located in Rio, Kiev, Bishkek, etc...at some point searched for world mobile coverage, but did not run into this map. thanks for the hints!
