Real-time network data show the restrictions in effect on Senegal’s leading mobile provider Orange (Sonatel) with restrictions subsequently also observed on Free (Tigo). The study is taken from a sample size of 4000 measurements from 120 vantage points across Senegal. Unrelated platforms have remained available without restriction. This class of disruption can be worked around using VPN services, which are able to circumvent government internet censorship measures.

4 June: Restriction of mobile data in Senegal

On 4 June 2023, authorities imposed a mobile internet shutdown in some areas, further limiting access to communications. The measure is implemented to prevent the “dissemination of hateful and subversive messages in the context of public order disturbances” per authorities, and has adopted a curfew-style daily cycle of disruptions. Such measures leave users fully offline and cannot be readily circumvented by use of a VPN.

What’s happening in Senegal?

Ousmane Sonko, a prominent opposition figure in Senegal, has been sentenced to two years in jail on charges of “corrupting youth,” leading to widespread protests in Dakar and other major cities. The court acquitted Sonko of rape and death threat charges but found him guilty of immoral behavior towards individuals younger than 21. The sentence could potentially bar Sonko from running in the upcoming presidential election. Protests have broken out in response to the verdict, with Sonko’s supporters claiming the charges are politically motivated and part of a plot to stymie his political career

Senegal has a history of using social media restrictions to control protests. In 2021, NetBlocks found that authorities limited access to social media and messaging apps, in addition to measures targeting traditional media. However, the new censorship measures are the most severe observed in the country to date.

Senegal’s government has also faced a series of activist cyberattacks over the treatment of Sonko, which brought down several state websites and online platforms hosted on the government ADIE network earlier in the week.

NetBlocks recommends against the use of network disruptions and social media restrictions, given their disproportionate impact to fundamental rights including freedom of expression and freedom of assembly.

Methodology

Internet performance and service reachability are determined via NetBlocks web probe privacy-preserving analytics. Each measurement consists of latency round trip time, outage type and autonomous system number aggregated in real-time to assess service availability and latency in a given country. Network providers and locations are enumerated as vantage point pairs. The root cause of a service outage may be additionally corroborated by means of traffic analysis and manual testing as detailed in the report.
