The average IPDV for the period 2/1/20 through 2/28/20 was 0.16+-0.07 msec. while for the period 3/1/20 through 3/31/20 was 0.16+- 0.06 msec.
For Ireland PingER monitors 3 hosts. One is planchet.heanet.ie, that is connected to SLAC via ESnet, GEANT and HEANET, all high-performance research and education networks. The other two are speedtest hosts that are used to enable the public to test the speed of their network connection. Looking at the chart below it is seen that the two Speedtest hosts track one another fairly closely while the HEANET host has a different trajectory. Interventions that might be expected to impact network performance include: Mar 12 shutdown schools, colleges and cultural institutions, Mar 24 almost all businesses, venues, facilities and amenities were shut. It is hard to see any noticeable correlation between these dates and IPDV performance. The spreadsheet is here.
