The same information is available in tabular format. We derive the conclusions listed below from the traceroute results gathered from monitoring sites located in Australia, South Korea, Taiwan, Pakistan, Burkina Faso, South Africa, Great Britain, United States, Mexico and Bolivia.

  • East and Central Africa is mostly connected via satellites.
    • Most of the routes in this case are via US. For example traffic to Angola transits via UK, US and a Satellite provider. Same is the case for countries such as Rwanda and Uganda.
    • Access to Sudan is extemely poor. The routes from all monitoring sites mostly transit via US>CA>CN>SA or GB>US>NL>SA. For example, access from Burkina Faso is via Morocco, Spain, Great Britain, China and finally Saudi Arabia.
    • Cameroon is the only country which is accessible via short short routes due to direct connectivity with France.
  • Connectivity from the world isn't as bad as it is within the region. The lack of IXPs is evident from the fact that Burkina Faso has Nigeria, Benin, and Mali as neighbours, yet the traffic transits via Morocco>Germany>US>Sweden>Norway,  Morocco>France and Morocco>France>Ivory Coast respectively.
    • However there are exceptions such as South Africa being directly connected to Botswana, Lesotho and Mozambique.
    • Other than that traffic is generally routed via US, GE, GB or US, SW, NO.
  • Routes to countries such South Africa, Senegal, Mozambique and Cameroon are direct.
