Minimum RTTs of <~ 400ms are typically a signature of a geostationary link. Looking at the minimum RTTs to African countries and comparing 2009 with 2010 one can see the impact of the new fibres fibre/terestrial routes in particular for East Africa in the apparent reduction of minimum RTTs below 400ms for several countries.

BGP Prefixes
The Border Gateway Protocol (BGP) backs the routing decisions on the Internet. It maintains a table of IP networks or 'prefixes' which designate network reachability among autonomous systems (AS). Thus the number of prefixes is roughly the number of networks that appears on the Internet. The number of BGP prefixes for Africa is shown below. The data is from BGPMon and there is a spreadsheet here. It is seen that for Africa Egypt leads by a factor of about two over South Africa (the country with the second most BGP prefixes). It is also seen that when one compares Africa with the rest of the world it has fewer networks than all other regions both for IPv4 and the upcoming IPv6 prefixes (note the number of African countries with no IPv6 prefixes).
