MainOne, a major data provider for most Nigerian banks, suffered a major fibre cut in Ghana that has knocked many major Nigerian banks offline, according to internal communication sent to bank staff and seen by TechCabal. As a result, customers of major Nigerian banks cannot access their banking apps or use any USSD service.

“A technical team is actively working on a solution,” someone familiar with MainOne’s business told TechCabal.

A spokesperson for TechCabal declined to comment on the situation.

Thursday’s internet outage extends beyond Nigeria, with South African internet users also experiencing slow speeds and unresponsive internet. According to news24, Vodacom confirmed that multiple subsea cable failures between South Africa and Europe were impacting several network providers.
