- Sudan shifted from average rtt of approx. 685 ms to approx. 260 ms in Nov 2004. This is a classic case of shift from Satellite to Fiber. However there is are no remarkable trends visible in the throughput or packet loss which may be due to congestion in the Fiber Link.. This is explained by the increase in packet loss over the same period of time. Thus the improvement in rtt was compensated by the increase in packet loss and the overall throughput fails to show any meaningful increasing trend.
- Mauritania shows interesting behaviour. One of the hosts we monitor (www.pmd.mr) shows improved connectivity around Jan 2006 indicating a shift from satellite to landline. However the other host (www.maurifemme.mr), which is indicated as being on satellite and located in Norway (courtesy http://www.geoiptool.com) is showing the same rtt of around 680+ ms. If this host is actually in Mauritania then we can conclude that some parts of the country have shifted to fibre but others are still on satellite.
- In addition the throughput and packet loss for the both hosts show marked improvement since Jan 2006 which indicates better connectivity.
