In this case study we look at the current state of Internet access for Africa as measured by the PingER project and also at the effect of the new submarine cable connections on the RTTs to countries of Africa as seen from SLAC National Accelerator Center near San Francisco. Even though we did not observe dramatic changes in performance, yet we believe that a significant impact will be observed once THe main effects seen so far are on the RTTs for selected sites that have converted to using the terrestrial links. As the new routes stabilize and more and more customers, e.g academia and commercial organizations, subscribe to the service, we can expect to also see lower losses and jitter and higher through-puts together with a wider impact on deployment.

PingER monitors over 165 sites in 50 countries, that contain about 99% of Africa's population. The African countries that are not currently monitored are Chad, Comoros, Equatorial Guinea, Sao Tome & Principe and Western Sahara. The results from PingER are used heavily in this study. Below is seen a map of the PingER sites in Africa. The red dots indicate PinGER monitoring sites, the blue are beacon sites that are monitored by most of the over 40 PingER monitoring sites around the world, and the green are other sites monitored by at least one monitoring site.
