Figure 1 shows the packet loss to various regions of the world as seen from N. America. Since losses are fairly distance independent no attempt has been made to normalize the data. It is seen that the world divides up into two major super-regions: N. America, Europe, E. Asia and Oceania with losses below 0.1%, and Latin America, C. Asia, Russia, S.E. Asia, S. Asia and Africa with losses > 0.1% and as high as as a few per-cent. All countries are improving exponentially, but Africa is falling further behind most regions. In general, the packet losses have declined by almost 45% each year. However the progress for Africa and South Asia has been much slower.
The minimum RTT shown in Figure 2, is distance dependent. The RTT to North America is artificially low as the measurements are made from North America. 
The large step for S. Asia in 2003 was due to the change over from satellite to fibre. as the result of gradual shift from Satellite to fiber. Central Asia (also Afghanistan) has hardly moved in its minimum RTT since it continues to use geostationary satellites.
