European data center firm Portus has topped out its latest facility in Munich, Germany.

The company topped out MU2 last week. The facility will offer 5.5MW and feature liquid cooling.

Portus broke ground on the 2,200 sqm (23,680 sq ft) MU2 in September. Developed alongside Mercury, the data center is due live in early 2027 and will take the campus to 7MW.

Arcus Infrastructure Partners formed Portus in 2024, rolling up Luxembourg's European Data Hub with German operators SDC SpaceNet DataCenter and Internet Port Hamburg.

The company is expanding all three sites and is looking for further buy-and-build opportunities across Germany and neighboring countries.

In Munich, Arcus acquired SDC SpaceNet DataCenter GmbH & Co, KG (SDC) from German ISP SpaceNet AG.

Launched in 2019 and located in Kirchheim, Munich, the SDC data center offers 5,400 sqm (58,125 sq ft) of data center space with capacity for 2,800 server racks. Telefónica Deutschland is a customer.

DCD spoke to Portus chairman Adriaan Oosthoek last year about how the company plans to compete in Europe.
