The Seacom undersea fibre optic cable plugging East Africa into high speed Internet went live Thursday July 23, 2009. See the BBC and CNN reports. Such a cable should dramatically reduce the cost of bandwidth measured in $/Mbps, and reduce the Round Trip Times (RTT) from >~ 480 ms for a geostationary satellite, down to 200-350ms by using shorter distance terrestrial routes. The minimum RTTs measured from SLAC to African countries in August 2009 is seen below. On the right is seen a map of the over 165 sites that PingER monitors in 50 countries in Africa. The red dots indicate PinGER monitoring sites, the blue are beacon sites taht that are monmitored by all monitoring sites, and the green are other sites monitored by at least one monitoring site.
