MainOne, a subsidiary of Main Street Technologies, was founded in 2010 to manage the building and operation of the privately funded Main One Cable System, stretching from Portugal to South Africa. Using the open access fiber backbone, the company soon diversified into colocation, managed hosting and cloud services.
In 2013, MainOne announced it would build a data center in Lagos that would be reliable enough to attract multinational companies which operate in Nigeria, but currently prefer do host their data outside the country.
MDX-i Data Center is a MainOne Company registered in Nigeria as MainData Nigeria Limited (MDXi). In January 2015, MDXi launched its flagship data centre project “MDXi Lekki” with the sole purpose of developing a hub for key intercontinental connectivity while serving as the primary point for traffic aggregation in West Africa. MDXI’s Lekki data centre is currently the largest purpose built data centre in the entire West Africa.
