A study by Ponto BR Information and Coordination Center (NIC.br) shows that the quarantine had an initial negative impact on the speed of internet access in Brazil. There was a partial recovery in speed after March 25, 2020, when the main streaming services decreased the quality of videos on their platforms in a preventive manner.
The number of user complaints registered with the National Telecommunications Agency (Anatel) grew 32% in the second half of March. The report is based on 970,676 measurements made in the period from January 31 to April 5.
The study detected a temporary reduction in download speed from March 18, when social isolation measures began to be implemented in states and cities, with a sharp drop in the week of after March 23, “reaching almost 10 Mbps [megabits per second] in decline”, says the report. The graphs illustrating the report (above) show that between March 14 and 19, the median download speed peaked at 23 Mbps. Between the 19th and the 23rd of the same month, the speed drops at a certain moment to just below 13 Mbps.
From March 25 onwards, download speed recovered partially to an average of 18 MBps.
