According to https://www.mining.com/sumitomo-halts-mines-in-bolivia-madagascar/ there was a curfew starting Thurs Mar 20 and 2 cities went into strict lockdown on the same date. Both hosts monitored in Madagascar are in the capital city of Antananarivo which has a population of 1.6 million or about 6.1% of the population of Madagascar. Within the two weeks before and after Mar 20 there does appear to be a v ery very slight reduction in the variability of the PingER IPDV measurements.

PingER monitors three hosts in Malawi. They are the Parliament of Malawi in the capital Lilongwe, (www.parliament.gov.mw), the Kamuza College of Nursing at the Queen Elizabeth Central Hospital, in Blantyre (www.kcn.unima.mw) and the University of Malawi - Malawi Polytechnic (www.poly.ac.mw) in Blantyre.
From https://en.wikipedia.org/wiki/COVID-19_pandemic_in_Malawi the main interventions that might be expected to impact network utilization were:
- both Both public and private education institutions were closed from 23 March
- President Peter Mutharika confirmed the country's first three cases of coronavirus disease 2019 on 2 April
- On 14 April, President Mutharika announced a 21-day lockdown starting Saturday 18 April at midnight.[17] However, on 17 April, the Malawi High Court temporarily barred the government from implementing the 21-day lockdown following a petition by the Human Rights Defenders Coalition
There is a sustained increase for a few days in IPDV seen by the University of Malawi on Mar 23, however a similar rise was seen the week before. Similar rises were also seen by www.parliamen.gov.mw. There also appears to be reduction in the overall magnitude and also the variability of IPDV for all hosts or 2 weeks after Apr 19.
- 4 April, suspended all public meetings, gatherings and conferences;
- From 8 April, the Lilongwe City Council placed a temporary ban on the opening of bottle stores, pubs and night clubs, sports clubs and gyms, street processions, wedding receptions, bridal showers, birthday parties and any other social gatherings or public events.
- On 9 April, Government announced more restrictions on entertainment, public events, markets and religious gatherings; • Schools, colleges and universities remain closed since 23 March;
- On 14 April, President Mutharika announced a 21-day lockdown starting Saturday 18 April at midnight.[17] However, on 17 April, the Malawi High Court temporarily barred the government from implementing the 21-day lockdown following a petition by the Human Rights Defenders Coalition
There is a sustained increase for a few days in IPDV seen by the University of Malawi on Mar 23, however, a similar rise was seen the week before. Similar rises were also seen by www.parliamen.gov.mw. There is a reduction in the overall magnitude and also the variability of IPDV for all hosts for 2 weeks after Apr 19 following the proposed lockdown. However, we can find no change in interventions around this time.
Looking at the 14 day rolling average and standard deviations of the IPDV measurements for www.parliament.gov.mw chart below, we see a roughly factor of 2 drop in the average and standard deviations around the proposed April 18 lockdown.
Mauritius
PingER makes measurements to two hosts in Mauritius. One is www.utm.ac.mu at the University of Technology Mauritius in the capital Port Louis. The other is www.groupeunion.mu the Groupe Union Mauritius, in Riche en Eau, Mauritius. They track one another closely.
