On Aug 1, 2009 at about 23:00 hours GMT the RTTs averaged over a day, from SLAC to www.ternet.or.tz changed from about 730ms to about 350ms (see below, note that the RTTs are truncated at about 900ms ). After about half a day it reverted back again. The traceroute when the RTT had reverted back shows the route going through Telia and Newskies, a satellite services provider. The traceroute when the RTT was low was via ESnet to San Joze where it was picked up by Teleglobe to take the traffic to London and thence to Tanzania where it was passed to Tanzania Telecommunications.
On August 3, 15:00 hours www.ku.ac.ke dropped to about 370ms (see below), the earlier step change from 650ms to 550ms may have been since only one direction of the route was using the terrestrial line. A traceroute after the changeover shows the route going via ESnet to New York and via Level3 onto London, there it is transferred to InterRoute and is carried to Kenya by Seacom and thence to Nairobinet.
