LuxConnect S.A. is a Luxembourg government-backed data center and dark-fiber operator that sells colocation space — rack, cage and infrastructure-as-a-service — across four multi-tenant, carrier-neutral facilities on two campuses in Bettembourg and Bissen, totaling roughly 14,700–15,000 m² of net IT space that the company states it owns 100%. Founded in 2006 with the Luxembourg State as sole shareholder, LuxConnect also built and operates over 1,800 km of national dark fiber connecting Luxembourg’s commercial data centers, and its Bissen campus hosts the national EuroHPC supercomputer MeluXina, run by its subsidiary LuxProvide. As of 2026, a new AI-optimized supercomputer, MeluXina-AI, built on liquid-cooled NVIDIA GB200 NVL4 Blackwell GPUs, is being deployed across LuxConnect’s dual Bissen and Bettembourg sites as part of the Luxembourg AI Factory initiative. LuxConnect’s facilities are Tier II to Tier IV certified by the Uptime Institute and are positioned for low-latency connectivity to Amsterdam, Frankfurt, Paris and London from the heart of Western Europe.
