Cirion Technologies is a colocation and cloud infrastructure provider operating across Latin America, formed from the Latin American assets of Lumen Technologies (formerly Level 3/CenturyLink) and backed by investment firm Stonepeak. As of 2025-2026, Cirion describes itself as operating a carrier-neutral data center platform across 7 countries in Latin America, with roughly a dozen main facilities plus edge sites, over 4,900 cross-connects, and more than 100 connected carriers and cloud on-ramps. The company sells colocation, bare metal, private cloud, and managed hosting services under a self-described “Core, Compute, Manage, Connect” framework, and it explicitly states it owns and operates its network and data center portfolio rather than reselling capacity. Its most distinctive recent move is a push into AI-ready, high-density infrastructure: new 20MW-class facilities in Santiago (SAN2) and Lima (LIM2) are marketed as “AI Native” with liquid-cooling capability, and its flagship Buenos Aires site is being expanded specifically to support intensive AI workloads.
Cirion Technologies operates as a cloud provider and colocation provider, with facilities at the following locations:

Yes. Cirion's newer LIM2 facility in Lurín, Lima, is marketed on its own website as "AI Native" with the capability to install liquid cooling systems, and the company has announced expansions at its Buenos Aires (BUE1) data center specifically designed, per its VP of Data Centers, to support intensive AI workloads with more than 20MW of added capacity.
How many data centers does Cirion Technologies operate?
Cirion has described its portfolio in slightly different ways over time; a 2025 press statement cited 12 main carrier-neutral data centers plus 10 edge data centers across 7 countries, while earlier releases and third-party trackers referenced 18 data centers across the region as of 2023-2024.
Where is Cirion Technologies headquartered, and where did it come from?
Cirion is headquartered in Miami, Florida, and was created when Lumen Technologies (formerly Level 3/CenturyLink) sold off its Latin American operations, with the resulting company backed by infrastructure investment firm Stonepeak.
Is Cirion a colocation company, a cloud provider, or both?
Both: Cirion sells colocation and interconnection space that customers can rent for their own hardware, and it separately sells bare metal and private cloud compute services, positioning itself as a combined digital infrastructure platform rather than a single-product provider.
