PingER was originally set up for monitoring connections between High Energy Physics (HEP) sites that were mainly at National Labs and Universities in the US, Canada, Europe and Japan. Thus these regions tend to have hosts that are mainly Research or Educational (R&E). As a result, for the above regions, most hosts being R&E have high-performance network links as opposed to public network links. Another reason pointed out to me by Wade Hong of Carleton University is "Due to the students in residence being asked to vacate for social distancing. With many university LMSes (Learning Managemnentnow cloud-based, and the use of
cloud media services for streaming of recorded content, the potential bottlenecks have moved from the institution to these services.
Thus looking at the overall performance for a country in these regions there is little evidence of the impact of Covid-19 interventions, See, for example, the analysis for Spain and Italy, two countries that were badly impacted by Covid-19. Also, see the UK.

To get a better idea of the overall impact we looked in more detail at 18 major countries in Africa that included 62 monitored hosts . in Southern Africa (Top Level Domains: ZA, LS, BW, NM), East Africa (BI, ER, ET, KY, MG, ML, MZ, RW, Sd, TZ, UG, ZM, ZW), and Central Africa (AO, CM, CD, GA)
- There was insufficient PingER data for 2 countries: Cameroon and Eritrea. Each had 1 host being monitored.
- There was also 1 host in Mozambique and 2 in Botswana that had insufficient data to draw any conclusions.
- We could find no interventions of the above kind for Burundi (2 hosts), Eritrea (1 host), Mozambique (4 hosts) and Rwanda (1 host).
- Of the remaining 51 hosts, 24 had noticeable IPDV changes within a week of the start of an intervention.
