CyrusOne

Profile narrative

CyrusOne provides data center colocation and interconnection services to a range of enterprise and wholesale customers. Its offerings include powered floor space, cooling, network connectivity, and managed services that support cloud access and hybrid IT environments. The company serves sectors such as finance, healthcare, technology, and content delivery, enabling customers to locate critical infrastructure within carrier‑neutral facilities. By maintaining a focus on reliable power and environmental controls, CyrusOne aims to meet the uptime requirements of mission‑critical workloads. Its platform is designed to support both retail and wholesale colocation models.

CyrusOne is headquartered in the United States and operates a portfolio of data center campuses across multiple geographic markets. As a real estate investment trust (REIT) listed on the New York Stock Exchange, the company structures its business around the ownership and leasing of purpose‑built data center real estate. This organizational form allows it to raise capital for facility development while providing investors with exposure to the data center infrastructure sector. The firm’s scale is reflected in its ability to deliver services to customers ranging from single‑tenant enterprises to large cloud providers.

A distinguishing attribute of CyrusOne is its emphasis on carrier‑neutral connectivity, which enables customers to interconnect with multiple telecommunications and cloud providers within the same facility. The company has highlighted cybersecurity risk management in its regulatory disclosures, noting ransomware as a documented business threat prior to the 2019 incident. In December 2019, a ransomware attack attributed to the REvil group affected six managed service customers hosted in its New York data center, prompting a forensic investigation and engagement of law enforcement while its colocation services remained operational. This event underscored the importance of the firm’s ongoing security practices and incident response capabilities.
