On Aug 2, 2009 following an email from Don Riley who had detected that kdn.co.ke had dropped to 370ms. We were Unfortunately not monitoring kdn.co.ke. However on further investigation we found the RTT from SLAC to acheraarchitects.co.ke had changed between 14:00 and 17:00 hours 6/1/09 GMT from a steady 716 ms to a steady 325ms. This is exactly what one would expect as the route moves from a GEOS to a terrestrial line. The plot below shows the average RTT time series:
The traceroute from SLAC to Kenya went via ESnet to Sunyvale, then via Level3 to New York and London and thence to Kenya. The RTT between London and Kenya was about 200ms.
