Introduction
Using PingER data and comparing the various metrics it provides, we ascertained that the most stable and yet sensitive metric in detecting changes caused by Covid-19 interventions was the Inter Packet Delay Variation (IPDV). The data below are for 120 days starting around January 16th and ending May 14th, 2020. For each country, there is 1 point per day. Only weekday data is shown in order to reduce the variability of the data and to focus more on the effect of interventions such as closing the workplaces, schools, universities, people working from home, or being out of work. The data was divided up by region in order to reduce the number of countries in a single chart. This is done so as to allow separation by eyeball of the IPDV lines for the various countries in a chosen region. For each region, we show one or more charts of the daily median IPDV. The intervention data is from Wikipedia (e.g. https://en.wikipedia.org/wiki/COVID-19_pandemic_in_Egypt).
We are looking for a significant rise or fall in IPDV possibly correlated with an intervention.
