Internet users across South Africa are experiencing frustratingly slow wifi and broadband connections due to major infrastructure challenges affecting the region’s primary undersea cables. The widespread connectivity issues stem from essential maintenance work on critical submarine cable systems, impacting both home and business users nationwide.
Current Network Disruptions
The West Africa Cable System (WACS) is undergoing crucial maintenance from June 1 to June 16, 2025, causing significant internet slowdowns across South Africa. This maintenance period addresses a faulty Branching Unit near Namibian waters, resulting in reduced network capacity and slower connection speeds.
Regional Impact Assessment
Cape Town and the Western Cape region are experiencing more severe wifi slowdowns compared to other areas. This heightened impact is due to their heavy reliance on West Coast cable infrastructure for international connectivity.
Internet Service Providers (ISPs) with redundant capacity through alternative cable systems are managing to maintain relatively stable connections. However, many users continue to face:
- Reduced download and upload speeds
- Higher latency in international connections
- Intermittent service disruptions
Historical Context
South Africa’s wifi slow-downs are part of a broader pattern of submarine cable challenges in 2024-2025:
- March 2024: Multiple cable cuts affected WACS, SAT-3, ACE, and MainOne
- May 2024: East African cable systems experienced damage
- February 2024: Anchor-related cable breaks disrupted services
Mitigation Strategies
To manage slow wifi connections during this period, South African users can:
- Switch to mobile data when available
- Schedule large downloads during off-peak hours
- Contact ISPs about alternative routing options
Looking Forward
While South Africa’s slow wifi situation is temporary, the recurring nature of submarine cable incidents highlights the need for increased infrastructure redundancy. Users should expect normal service restoration after the maintenance period, weather conditions permitting.
