Internet shutdown in the Republic of the Congo on election day

NetBlocks metrics confirm an internet blackout in the Republic of Congo on the day of presidential elections, Sunday 21 March 2021. The incident has a recorded duration of three days.

Metrics show a near-total loss of connectivity from just around midnight local time on the morning of the elections. The internet disruption continued as polling took place and as votes were counted, and service was not substantially restored until after election results were announced on Tuesday night.

The incident follows a pattern of election day internet shutdowns in Congo-Brazzaville, with a similar information blackout imposed by authorities during March 2016 presidential elections.

Incumbent President Denis Sassou Nguesso, in power for a total of some 36 years, prevailed to take a fourth term as predicted at the polls, which were panned for their lack of transparency.

Work is ongoing to monitor and evaluate the incident.

This report follows the NetBlocks Election Pathfinder Rapid Response methodology which defines a set of core principles, workflows and benchmarks for network measurement and evaluation during elections and referenda.

NetBlocks diffscans, which map the IP address space of a country in real time, show internet connectivity levels and corresponding outages. Purposeful internet outages generally have a distinct network pattern used by NetBlocks to determine and attribute the root cause of an outage, a process known as attribution which follows detection and classification stages.
