In this case we tried smoothing the data with a running average over the last week (7 days bearing in mind that since we only recorded weekdays only 5 days were joined in the running average). This also means that the days shown at the bottom are in some sense 7 days ahead of the data.
Brazil
PingER monitors 14 hosts in Brazil. Eight are connected to SLAC by high performance Research and Education (R&E) network links traversing ESnet, AMPATH, RNP and FAPERT. The other six are connected by public networks.
- Brazil R&E hosts: www.impa.br in Rio de Janeiro, www.linea.gov.br and ms01.linea.gov.br in Rio de Janeiro, access.sprace.org.br in Sao Paolo, if.ufrj.br and pinger.ifrj.br in Rio de Janeiro, ping.unesp.br and www.unesp.br in Sao Paolo
- Brazil public hosts: ns.dns.br in Brasilia , www.globalone.com.br in Brasilia, www.inetvr.com.br in Salto in the state of Sao Poalo, www.mpaal.org.br in Sao Paolo, www.registro.br in Brasilia, www.uern.br (Universidade do Estado do Rio Grande do Norte )
According to https://en.wikipedia.org/wiki/COVID-19_pandemic_in_Brazil, The first case in Brazil was Feb 25, Mar 17 was the first death. There have been no nationwide closures of schools, just local. On 18 March, Rio de Janeiro and five other municipalities—São Gonçalo, Guapimirim, Niterói, Nova Iguaçu, and Mesquita—in the state of Rio de Janeiro had declared a state of emergency to help contain the coronavirus. Mar 20, the government of Rio Grande do Norte declared a public emergency situation. Mar 21 the State of São Paulo declared a state-wide quarantine. All commerce and non-essential services were to close 24 March.
We divide the PingER data for Brazil into two sets. One for Brazilian R&E hosts and the other for non R&E or public hosts. For several hosts, there is a change in behavior starting around the same time as the interventions mentioned above.
- www.globalone.com.br has a strangely high IPDV until late February.
- Starting Mar 16 the IPDV to www.uern.br in Rio Grande do Norte increases by over a factor of 2 for over a month
- The hosts ns.dns.br and www.registo in Brasilia track one another both seeing an increase in IPDV starting Mar 12
- The R&E host access.sprace.org.br has a strangely high IPDV
- The two R&E hosts at UNESP in Sao Paolo track one another fairly closely both seeing a spike in IPDV Mar 11 followed by a sustained increase until the end of April
- The two linea.gov.br hosts track one another closely as might be expected. From Feb 1-Mar 17, the average IPDV of the two linea hosts is 0.29+-0.07msec, whereas from Mar 18 thru Apr 1 the average drops to 0.075+- 0.07msec.
