Impact
Main One provides international capacity into a region that has experienced explosive growth in tele-density in recent years, but which remains constrained with respect to access to international cable capacity for global connectivity.
The Main One Cable system provides open access to regional telecom operators and Internet service providers at rates that are less than 20% of current international bandwidth prices in the region available via SAT3 or satellite service providers, according to the project's organizers. Main Street says it will encourage local content development via skills transfer of critical networking technologies and job creation with the location of the network operational center (NOC) for the entire system in Nigeria.
Ownership
The cable is privately owned by Main Street Technologies, international investors like the
Africa Finance Corporation

and the Pan-African Infrastructure Development Fund (PAIDF) and a couple of Nigerian banks.
Acquisition
Equinix announced they will be acquiring Mainone for an enterprise value of $320m, the deal is expected to be completed in the first quarter of 2022.
