CyrusOne Starts Construction on First Italy Data CenterI Outside Milan

CyrusOne has broken ground on its first data center in Italy. The company this week announced it has officially broken ground on MIL1 in Milan. The three-story facility will deliver 27MW of IT capacity across 7,000 sqm (75,345 sq ft) of technical space, with the first phase expected to go live by Q3 2027.

"Milan is an increasingly important digital infrastructure market for Southern Europe, and this development marks a key milestone in our European growth strategy,” said Andreas Paduch, managing director, Europe at CyrusOne. “With MIL1, we are establishing a strong platform in Milan to support our customers’ long-term capacity and connectivity needs. This project is only possible through close collaboration with our partners, including the Municipality of Segrate and our wider delivery ecosystem, whose support and expertise are critical to bringing this development to fruition.”

CyrusOne unveiled plans for its first Italian data center in December 2024, securing an 18.5-acre site in Segrate, east of Milan. A second facility, the 54MW MIL2, is also planned for the location. MIL1 is designed to capture and reuse waste heat, initially for on-site use, with the potential to support a future district heating network.

“The start of construction on the CyrusOne data center marks a significant step in the development of Segrate and strengthens our city's role as a leading hub for innovation and digital infrastructure,” said Paolo Micheli, Mayor of the Municipality of Segrate. “An investment of this magnitude enhances the area, as it finally allows for the regeneration of a vast, problematic industrial area that has been abandoned for decades, replacing it with a prestigious project with a lower environmental impact than previously considered alternatives.”
