It can be seen that NRENs are being created and that in September 2008 most traffic to the rest of Africa took costly international links to get outside South Africa. More details on the routes to African countries from several measurement points around the world measured in Spring 2009 can be seen in a spreadsheet.
Initial Results
One would expect with the use of a terrestial fibre rather than a geo-stationary satellite that the minimum RTT woud be reduced from >=40ms to 200-300ms as seen from the US. Also the reduced congestion enabled by the higher speed links should make the average RTT more stable and reduce the packet loss. Below are shown the average RTTs and losses from SLAC on the West Coast of the US to various hosts on the East Coast of Africa. These are all measured using the PingER project's data.
