"Republic of Congo: Opponent dies of COVID-19 on day of presidential election", 22 March 2021

... Voting continued on presidential election day on Sunday after access to the internet and social networks were cut in the Republic of Congo, where long-standing President Denis Sassou N'Guesso is seeking a new five-year term.

"Network data show a near-total collapse of national connectivity from midnight local time. The incident is ongoing as polls are due to open," the London-based tracking service Netblocks reported.

AFP journalists also noted that the internet access stopped shortly after midnight on Saturday and was still down as polling stations opened on Sunday.

The Congo Republic's 2016 presidential election, which Sassou N'Guesso won with 60% of the vote, was also marked by a communications shutdown.
