What LuxConnect does

LuxConnect S.A. is a private Luxembourgish infrastructure operator founded in October 2006 and wholly owned by the Luxembourg State. It runs four Tier IV certified, Uptime Institute-rated data centers across two sites — DC1.1, DC1.2 and DC1.3 in Bettembourg plus DC2 in Bissen — delivering approximately 15,000 m² of owned server space, colocation services from single racks to dedicated rooms of up to 324 m², and managed services including remote hands, managed connectivity, and disaster recovery. Alongside the data center business, LuxConnect owns and operates Luxembourg's national dark fiber backbone of 1,900 km with 16 international breakouts to Belgium, France, and Germany, marketed as wholesale transport for telecom operators and a "wholesaler's wholesaler" backbone. The infrastructure stack is differentiated by a carrier-neutral model hosting 40+ national and international carriers, renewable energy sourcing (100% hydroelectric via certified green certificates), and a proprietary energy stack built around Kiowatt trigeneration cooling and waste heat recovery that delivers an average PUE of ~1.4 (best 1.30) with WUE 0.206 l/kWh and CUE 0.034 kg CO₂e/kWh.

The company monetizes primarily through recurring subscriptions: tiered colocation pricing on space, power density (up to 10 kW/rack) and redundancy, monthly dark fiber leases to operators and public authorities, and HPC capacity allocation through its wholly owned subsidiary LuxProvide, which operates the 18-petaflop MeluXina supercomputer plus upcoming MeluXina-AI and MeluXina-Q systems. A 60/40 joint venture with Proximus called Clarence extends the business into Europe's first operational sovereign disconnected cloud. Customers span national and foreign telecom operators, Luxembourg public authorities and municipalities (Cities of Differdange, Dudelange, Ettelbruck, Luxembourg City), Tier 1 carriers (Orange, BT, NTT, Colt, Cogent, Verizon), broadcasters (BCE), healthcare organizations (via HDS certification), SMEs and start-ups (via HPC access), and enterprise ICT firms. Distribution is direct enterprise sales plus partner-delivered managed services, with a self-service customer portal for account and access management.

Financially, LuxConnect reported EUR 42M in revenue in 2024 (+20% YoY) and EUR 42.5M in 2025 (broadly stable), with net profit of EUR 9.8M in 2025 (+12.6% YoY) — a record result. The current organization has ~31 employees, but a new administrative headquarters foundation stone laid in February 2025 in Bettembourg (5,000 m², up to 250 workstations, completion targeted end-2027) signals a planned step-change in organizational scale, alongside ongoing investments in HPC/AI/quantum capacity, three-level EV-ready parking (2026), and membership in the Climate Neutral Data Centre Pact committing to PUE 1.3 and 100% clean energy by 2030. Leadership comprises CEO Paul Konsbruck, CTO Vincent Weynandt, and (since June 2025) Chairman Michel Asorne, Deputy Director at the Ministry of State's Department of Media, Connectivity and Digital Policy.
