At the moment the SAT-3/WASC/SAFE fibre has been in place for some time and connects up several countries on the W. Coast of Africa. Up until now however, there have been no fibres on the East Coast of Africa. The Seacom line is not the only fiber-optic cable project on Africa's East coast — others include the Eastern Africa Submarine Cable Systems (EASSY), The East African Marine System (TEAMS)and Lion — but it will be the longest and have highest capacity (1.28 terabytes per second). The EASSY and TEAMS are designed to build out African telecommunications networking, but Seacom is the only line that directly will connect east coast urban areas in Kenya, Madagascar, Mozambique, South Africa and Tanzania to France and India. TEAMS landed in Mombasa early June 2009 and is currently undergoing testing while EASSY and Lion are expected to be operational by mid-2010. Maps of the various fibres is shown below and , more details are available here. Also shown is network schematic of the Seacom link.

BY August 3rd, the average RTT from SLAC to mail2.starcom.co.ug in Kampala Uganda reduced from about 780ms to about 540ms. On August the average RTT dropped further to about 380ms. Possibly in the intermediate state (540ms) only one direction was using the fibre. . The traceroute measured on 8/15/09 shows the route going via ESnet to Sunnyvale then onto San Jose and Level3 that carries it to New York and London, the next hop is in Nairobi an Intersat Africa node. Hop 18 is also in Nairobi and hop 19 in Kampala.
