Johannesburg Data Centre (JB1 East & West)

Isando, Johannesburg

Opened in January 2010, the first phase of JB1, the Johannesburg based colocation data centre environment was originally set over 1250sqm. Growth in the market required further expansion phases that increased the colocation data centre floor space in JB1 East to over 3 850sqm. Continued demand for Teraco's neutral colocation services has resulted in the building of a second facility, JB1 West, which houses over 5000sqm of data centre floor space and resulted in a total of 20MVA of power supplied to the site.

Teraco is currently in the process of constructing a third facility in Johannesburg, JB2 - Bredell. Watch this space closely and follow us on social media for further details of the new site.
