RadiusDC: Miami I

In 2024, RadiusDC revealed its purchase of Miami I, a highly connected data center in the South Florida region, situated in Sweetwater, Florida. The facility was acquired from NextStream, a Latin American data center company under Actis ownership.

• The site was formerly managed by Telefonica until Nabiax acquired it in 2020. On 13 June 2023, Nabiax sold its American-based data centers to the investment fund Actis.

Miami I consists of a two-floor structure offering 173,500 square feet of data center capacity, engineered to endure Category 5 hurricane-force winds. Backed by IPI, RadiusDC intends to promptly enhance Miami I's capabilities through additional investment. RadiusDC is fitting out two data halls on the second floor: the first 3 MW hall is projected to come online in Q1 2027, with a second 3 MW hall following in Q2 2027, on a path to 12 MW across the two halls.

Originally built for Telefónica's own uses, the telco sold a majority stake in its Latin American and US data centers to investment firm Asterion in 2019. Asterion then founded new operator Nabiax from the portfolio, with Telefónica as an anchor customer. Actis then acquired Nabiax’s Latin American data center footprint in 2023, taking over 11 data centers across six countries in Latin America and the US, and renaming the unit Nextstream.
