We made case studies of: the Democratic Republic of the Congo and Cuba upgrading from GEOS to terrestrial fibre optic links, and a comparison of PingER derived throughputs vs those of Speedtest.net (see https://confluence.slac.stanford.edu/display/IEPM/Comparison+of+Speedtest.net+download+speeds+versus+PingER+Derived+throughputs).
Worked with conatcts to fix up monitors at TRIUMF in Vancouver, Canada, DoE ASCR in Washington DC.
