In this space, companies like MainOne (now Equinix), Rack Centre, and WIOCC through its Open Access Data Centres (OADC), are investing heavily to strengthen Nigeria’s digital backbone. 

But which of them is best positioned to ensure growth across the Nigerian startups sector?

MainOne (Equinix): The Global Reach & Certification Anchor

MainOne has leveraged its submarine cable system, fibre optic network, and its acquisition by Equinix to offer reach and certified reliability. Its data centre arm, MDXi, holds the Uptime Institute Tier III Constructed Facility certification (TCCF), among several other certifications (PCI-DSS, SAP Infrastructure Services, ISO 27001 & 9001). 

Its Network Connect and Cloud Connect services link local branches or clouds with global infrastructure. For example, by routing traffic via its submarine cable and leveraging Equinix Fabric, it offers predictable performance and connectivity from Lagos to key global hubs.

Power reliability, a common pain point in Nigeria, is one of MainOne’s standout strengths. Its Lagos data centre integrates multiple power redundancies, utility partnerships, and high-capacity generators to maintain near-continuous uptime. That’s essential for startups whose businesses can’t afford downtime.

Still, MainOne’s premium-grade services usually come at higher prices. For small or growing startups, that might make it more suitable at later stages of expansion rather than at the beginning.

So, MainOne offers scale, high certifications, international interconnect, and relatively lower risk from interruptions.

Rack Centre: The Nimble, Neutral & Efficiency-Driven Option

Rack Centre carved its reputation as Nigeria’s first carrier-neutral Tier III certified data centre. Unlike most competitors, it is not owned by any telecom or internet provider, which gives clients the flexibility to interconnect with over 70 different carriers and ISPs. That neutrality is one of its biggest competitive edges.

Its location in Oregun, Lagos, provides direct access to all the major undersea cables serving Nigeria, including WACS, MainOne, Glo-1, SAT-3 and ACE. The result is low latency, strong redundancy, and smooth interconnection between local networks.

Rack Centre’s new LGS2 facility represents a huge step forward. The 12MW hyperscale and AI-ready centre is designed for exceptional energy efficiency and sustainability, with advanced cooling systems and a lower Power Usage Effectiveness (PUE) ratio. This reduces operational costs and aligns with global sustainability standards, an important factor for modern tech companies.

Its approach appeals particularly to startups seeking flexibility, local performance, and freedom from vendor lock-ins. However, Rack Centre’s challenge is scale: it has a solid local presence but lacks the global integration that Equinix offers through MainOne.

One of its strongest propositions is neutrality: Rack Centre is not owned by a telco, ISP or cloud provider; it does not compete with its tenants; therefore, there is less risk of vendor lock-in or conflict. 

For startups, especially those scaling fast, Rack Centre tends to offer strong locality benefits: low latency within Nigeria, strong peering via IXPN, predictable interconnects, and usually more flexible arrangements for rack space or interconnection.

WIOCC / OADC: The Pan-African Connector, Big Capacity Incoming

WIOCC, via its Open Access Data Centres (OADC) arm, is scaling aggressively. Its strategy is open access, hyperscale capacity, and linking regional networks. 

OADC’s expansion plan is one of the biggest in the sector. The company has committed over $240 million to expand its Lagos data centre to 24 megawatts by 2027, starting with a 12MW first phase. The facility is designed to support cloud providers, hyperscale clients, and growing tech firms that need capacity and cross-border connectivity.

WIOCC also launched OAfabric, its cloud interconnection platform, which allows businesses to connect directly to international cloud services through a simplified interface. Combined with its wide fibre and submarine network, it aims to provide both affordability and regional reach.

That said, OADC’s infrastructure in Nigeria is still relatively new, with much of its full capacity under development. The scale and potential are enormous, but the market will need to see consistent delivery over time.

Its strength is scale (once the full capacity is live), strong peering potential across borders, and an open access model that benefits ISPs, cloud providers and telcos who need wholesale connectivity.

Comparing Strengths and Trade-offs

Each company brings something unique to Nigeria’s digital economy. MainOne is on top when it comes to global integration and enterprise-grade reliability, backed by Equinix’s global standards. For Rack Centre, it’s in neutrality, local performance, and energy efficiency, making it ideal for startups prioritising flexibility and cost control. WIOCC, meanwhile, is building a network that could redefine cross-border connectivity and scale for Africa’s data economy once fully realised.

In terms of reliability, both MainOne and Rack Centre already provide strong uptime backed by Tier III certifications. MainOne’s international connectivity gives it an advantage for startups with global vision. Rack Centre provides a more accessible, locally optimised alternative for startups that value independence and direct peering with multiple providers. WIOCC is the long-term investment, its pan-African fibre network and future 24MW capacity could make it the infrastructure giant to watch.

What I Think Startups Should Care About Most

If I were advising a startup today, I would tell them:

• Get your foundation right: data sovereignty, uptime, and latency are not optional. Pick a provider with strong certifications and multiple power/fibre redundancy.
• Think about the cost-to-scale: what looks affordable at 10 racks may be expensive at 100. Check how interconnect charges, cross-connects, and peering fees scale.
• Be wary of lock-in. Providers that are carrier-neutral and open access give more flexibility to mix and match cloud, network, and hosting providers.
• Monitor sustainability and total cost of ownership. Facilities that waste energy or have unreliable back-up power may cost more when things go wrong.

Who’s Best Positioned?

Each of these providers has a part. If I had to pick:

• For startups already serving international customers or aiming to scale globally, MainOne/Equinix remains ahead because of its global interconnection, submarine cable reach, and certifications.
• For startups focused on Nigeria or nearby countries and needing lower latency, predictable interconnect and flexible arrangements, Rack Centre looks like a strong option.
• For companies needing wholesale capacity, cross-border reach, or anticipating rapid growth in cloud usage, WIOCC/OADC will likely pull ahead once their full capacity is available and stable.

In short: there is no single perfect choice. But the competition among these three is powerful for our ecosystem. Startups will benefit as they force better reliability, lower prices, and greater innovation. And I’m positive the fate of Nigerian startups looks brighter if we build this backbone well.

And for businesses, this gap means higher expenses, slower access to cloud services and limited ability to scale competitively.

Today, Open Access Data Centres (OADC), a WIOCC Group company, launched Open Access Fabric (OAfabric) in Nigeria (OADC Lagos) and the Democratic Republic of Congo, DRC (OADC Texaf – Kinshasa), to leapfrog these limitations and position Nigeria as Africa’s digital nerve centre.

With over 107 million internet users, Nigeria represents the continent’s largest digital market, but enterprises have long had challenges with high latency, expensive transit, and inconsistent local content access. 

The game-changing interconnection platform, OAfabric directly addresses these challenges, providing secure, low-latency connections, direct peering with global cloud providers, and integration with leading African IXPs, including IXPN in Nigeria and KINIX in the DRC.

Speaking at the launch, Dr Ayotunde Coker, chief executive officer of OADC, said “We designed OAfabric around the real challenges African businesses face. It is about solving problems – reducing the cost to compute, improving performance, unlocking access to cloud and content, and creating an environment where companies can scale with confidence while accelerating time to market.”

OAfabric is engineered to scale from 1Gbps to 100Gbps, supporting hybrid colocation architectures, AI workloads, and data-intensive applications. Traditionally, enterprises had to rely on the open internet, risking security breaches and inconsistent performance. Coker highlighted the platform’s protective advantage:

“Without OAfabric, if you want to go to the cloud, you basically have to go to the open internet. All of us understand the disadvantages of pushing your content into the open internet. Companies now have to start building layers of security, all the years of security. 

“But with OAfabric, it is a secured connection, structural cable connection from here all the way into the cloud environment, irrespective of where you are. So you are guaranteed that literally, for someone to hack, he has to use a source and come back in. It’s extremely secure connectivity.”

Resilient, Reliable, and Rapid

The platform’s resilience was demonstrated last year during a subsea cable disruption. OADC restored 2 terabytes of connectivity within 48 hours, a project that would normally take three months, stressing the network’s ability to maintain Africa’s digital backbone under extreme pressure.

Latency is dramatically reduced, a huge factor for enterprises in fintech, cloud services, and AI. Coker explained:

“We deliver a significant, well-reliable, low-latency connection. Latency between here and points in Europe, for instance, is significantly reduced. You can interconnect into Amsterdam, the UK, Marseille. We define with cloud providers exactly where we want to meet them and cross-connect very neatly, and it has a significant result on latency.”

Since 2018, OADC has expanded strategically across the continent. The Lagos data centre in Lekki currently operates at 2 megawatts, with plans to scale to 24 megawatts. 

Facilities in Kinshasa and four South African cities—Durban, Johannesburg, and Cape Town—serve as interconnection points for global subsea cables including Google Aquiano and 2Africa, creating a robust pan-African network.

Coker elaborated that “OAfabric gives us a more efficient way of delivering growth, not just in one direction, but with the capability to reverse the direction as we have more internet exchanges here, localising data. As we bring more actual cloud on-ramps into the country, we build the infrastructure for those hyperscale ramps to come here, and that’s what we’re doing.”

OAfabric aligns with Nigeria’s mega cloud policy, ensuring sensitive data remains within national borders while empowering local cloud providers to compete with international hyperscalers. It also opens the Nigerian market to foreign investment, enabling cloud edge zones and disaster recovery zones to be deployed with speed and confidence.

Head of Converged Open and Digital Infrastructure, OADC Africa, Obinna Adumike, explained the reach of OAfabric beyond Nigeria and DRC:

“OAfabric is big, and it’s here. We have a very robust connectivity network, and the biggest advantage of that is the fact that WIOCC network can connect you to any country in the world, but most especially the closest continents that Africa impacts on; Africa, Europe, America, and then within the continent, East Africa, Southern Africa and all of that. These are the regions that most of our cloud users either connect to, send, or collect traffic.”

Simplifying Complexity for Enterprises

For businesses, OAfabric transforms previously complex digital operations into seamless, manageable workflows. Coker expatiated this:

“Think of OAfabric as a box in a data centre. You connect to it, choose your pipe size—like deciding between a two-lane or four-lane highway—and your data flows efficiently to the cloud. The faster and more reliable the connection, the better the user experience.”

“OAfabric is not just infrastructure; it represents a shift in what is possible for Africa’s digital economy,” added Dr Coker. “By removing barriers and enabling seamless, high-performance peering between key ecosystems, including local and global Internet Exchange Points (IXPs), content providers, cloud platforms and enterprises, it provides the frictionless interconnection needed to access digital services more efficiently.”

With OAfabric live in Nigeria and the DRC, OADC is creating a resilient, secure, and scalable pan-African digital ecosystem, empowering enterprises, accelerating innovation, and defining a new era of African digital sovereignty.
