One host (www.aisha.ac.zm) of the 6 monitored in Zambia improved its RTT from about 720ms to 550ms on August 20, 2009 (see below). Also at the time of writing it looks like they are still moving the link over to the terrestrial lines since the performance is very unstable (high losses) and there are big changes in RTT. It is possible the link in one direction is using a GEOS while the other is an all terrestrial link and the large dips to 400ms are when both legs are using terrestrial links. We believe the terrestrial path goes via Botswana and Namibia. The traceroute from SLAC on 9/9/09 appeared to use a satellite link in at least one direction. On October 2, 2009 Mike Jensen reported that the traceroute from Rome to www.aisha.ac.zm was well below 450ms and thus appears to be a terrestrial link. However the tracreoute from SLAC was still taking over 550ms. Also the traceroute from TENET/Cape Town South Africa to www.aisha.ac.zm took over 650ms. The traceroute from NUST, Islamabad, Pakistan to mail.unza.zm takes less than 450ms and appears to be a terrestrial path going via Namibia. On October 7th 2009 the traceroute from SLAC to mail.unza.zm appeared to be terrestrial and went via Namibia.
The RTT to one host www.kie.ac.rw in Rwanda at the Institute of Information reduced from about 720ms to 360ms between the 22nd and 26th of Spetember 2009.
Malawi currently (10/13/09) has only GEOS access. The most likely terrestrial path will be via Mozambique to Maputo (the landing point for both Seacom and TEAMS) see the email from Bjorn Pehrson and the article by Telegeography.
