Using Motion Charts to look at PingER data versus Covid cases
Another attempt to correlate the impacts might be to use a Motion Charts tool to look for correlations between say Covid-19 cases (cases, hospital admissions, deaths etc) and PingER metrics as a function of time, by country, continent, plus population or density of population. The idea is that as Covid-19 cases pass say 100, the country will impose interventions such as school closing, social distancing etc. which will change the usage patterns of the Internet which may have noticeable impacts on the PingER measurements.
