More About CyrusOne
CyrusOne focuses on designing, building, and operating data centers used by enterprises, hyperscalers, and cloud providers that require predictable power, cooling, space, and connectivity for core IT and digital infrastructure. Its facilities host customer-owned servers, storage, and networking equipment, providing colocation (data center infrastructure) as the foundation for production, Disaster Recovery (DR), test, and development environments.
The company operates carrier-neutral data centers, which means customers can connect to multiple network service providers, internet exchanges, and cloud on-ramps within the same facility. This interconnection (network and cloud connectivity) capability is used to support hybrid cloud and multi-cloud architectures, where workloads span on-premises (on-prem) systems, private clouds, and public cloud platforms. Customers use cross-connects, meet-me rooms, and other connectivity constructs to integrate Wide Area Network (WAN), internet, and private interconnect links into their network architectures.
CyrusOne’s build-to-suit and dedicated data center offerings (data center infrastructure) provide facilities tailored to large-scale deployments, including hyperscale cloud and digital platforms that require high power density, large contiguous space, and standardized designs across multiple regions. These deployments typically support architectures such as distributed cloud, content delivery, Software-as-a-Service (SaaS) platforms, and large enterprise application estates, with an emphasis on predictable latency, capacity planning, and operational consistency.
The company’s services cover core data center infrastructure elements such as Uninterruptible Power Supply (UPS) systems, backup generators, diverse utility feeds, and mechanical cooling systems, along with physical security (access controls, surveillance, and visitor management) and environmental monitoring. These capabilities are used by customers to meet internal reliability objectives and to support regulatory or compliance requirements related to data hosting and physical security.
Within an enterprise IT taxonomy, CyrusOne fits into the colocation (data center infrastructure), interconnection (network connectivity), and dedicated data center (infrastructure outsourcing) categories. Its facilities are positioned as an alternative or complement to self-built enterprise data centers, and as a neutral platform where organizations can place infrastructure close to cloud regions, network hubs, and end users. Technical stakeholders evaluate CyrusOne in relation to capacity needs, power and cooling design, connectivity ecosystem, geographic footprint, and alignment with their hybrid IT and cloud strategies.
