Cirion Technologies is a pan-Latin American digital infrastructure provider selling colocation, interconnection, bare-metal, private cloud, and managed hosting services out of its own network of data centers spanning Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Peru, and Venezuela. As of 2025, the company operates roughly 18 carrier-neutral data centers organized as campuses in cities like São Paulo, Rio de Janeiro, Santiago, Lima, and Buenos Aires, several of which are undergoing multi-megawatt, AI-ready expansions. Formed in 2022 when investment firm Stonepeak acquired Lumen Technologies’ former Latin American operations for $2.7 billion, Cirion inherited decades of regional fiber and data center infrastructure built under Lumen and Level3, and has since rebranded and modernized that footprint while investing heavily in new high-density, hyperscaler-oriented campuses in cities such as Lima, Santiago, and Rio de Janeiro.
Cirion Technologies operates as a cloud provider and colocation provider, with facilities at the following locations:

Common Questions
Is Cirion Technologies building AI-specific data center capacity?
Yes. Cirion has explicitly designed several new facilities for AI workloads: its RIO2 campus in Rio de Janeiro is described by the company as being built from the ground up for AI workloads, its LIM2 facility in Lima and SAN2 facility in Santiago are described as natively supporting liquid cooling for AI-ready environments, and its BUE1 facility in Buenos Aires underwent a 2025 upgrade specifically to meet surging AI capacity demand.
Where did Cirion Technologies come from?
Cirion was formed in 2022 after Stonepeak, a New York-based infrastructure investment firm, closed a $2.7 billion acquisition of Lumen Technologies' Latin American operations, which had themselves descended from the older Level3/Impsat/IMPSAT regional network and data center assets.
How many countries does Cirion Technologies operate data centers in?
Cirion operates physical data centers in eight countries: Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Peru, and Venezuela, with additional non-data-center offices elsewhere in the region and in Florida, US.
Does Cirion sell cloud services or just colocation?
Cirion sells both: its platform is organized around four pillars — Core (colocation), Connect (interconnection), Compute (bare metal and private cloud with GPU support), and Managed (fully managed infrastructure) — letting customers buy physical rack space or consume cloud/compute services.
