MainOne, now operating as “MainOne, an Equinix company,” is a West African data center and connectivity provider whose colocation business (built and run through its subsidiary MDXi) spans Nigeria, Ghana, and Côte d’Ivoire. Equinix acquired MainOne and its MDXi data center unit for $320 million in a deal that closed in December 2021, giving Equinix its first physical data center footprint on the African continent. The company’s core product is carrier-neutral colocation space — private suites, cages, and racks — inside Tier III-certified facilities, anchored by a multi-building campus in Lekki, Lagos, alongside single facilities in Accra and near Abidjan. As of 2024, Equinix formally retired the MDXi brand and rebranded the data center assets under the Equinix name, while MainOne itself continues as the connectivity/ISP arm of the group.
MainOne has a confirmed data center presence at the following locations:

Common Questions
Is MainOne still an independent company?
No — Equinix acquired MainOne, including its MDXi data center subsidiary, for $320 million in a deal that closed in December 2021, and by October 2024 Equinix had rebranded the MDXi data center assets under the Equinix name while MainOne continues as the group's connectivity and ISP business.
How many data centers does MainOne/MDXi operate and where?
MDXi has operated facilities in Lagos, Nigeria (two campuses, Lekki I and Lekki II), Accra, Ghana (the Appolonia facility), and near Abidjan, Côte d'Ivoire, giving more than 5MW of combined capacity across Nigeria, Ghana, and Côte d'Ivoire as of 2022.
Does MainOne/MDXi offer AI or GPU-optimized data center space?
No specific, sourced evidence of GPU clusters, liquid cooling, or AI-factory infrastructure was found for any MDXi/MainOne facility; Equinix has stated ambitions to grow the Lekki campus to serve future hyperscaler demand, but this is a stated goal rather than confirmed AI-specific infrastructure.
Are MainOne's data centers carrier-neutral and certified?
Yes — MDXi describes its data centers as carrier-neutral, and its original Lekki, Lagos facility received Tier III certification from the Uptime Institute in 2018, a standard later repeated for the Appolonia, Ghana facility.
