Business Internet & Enterprise Connectivity in Luxembourg
Luxembourg hosts one of Europe's highest concentrations of Tier IV data centres per square kilometre — EBRC, LuxConnect (which also hosts the MeluXina supercomputer), and Portus (a fully underground, 100% renewable, carrier-neutral facility in the Cloche d'Or financial district). LU-CIX (Luxembourg Internet Exchange) is increasingly positioned as an alternative to Frankfurt, Amsterdam, and London for financial services peering. And the country's fund industry, international banking sector, and EU institutional proximity create persistent demand for high-resilience, compliance-ready connectivity.

How we deliver in Luxembourg
Luxembourg is a significant backhaul hub for our financial services clients. We route capacity from \[Zurich\](/countries/switzerland) and \[Geneva\](/countries/switzerland) to Luxembourg, and from Luxembourg to \[Frankfurt\](/countries/germany), \[London\](/countries/uk), and \[Paris\](/countries/france) — the four major European financial data centre corridors. These aren't point-to-point circuits managed by different providers; they're a single programme managed under one relationship with consistent SLAs across every hop.
We deliver via POST Luxembourg, Tango, Colt, and LuxNetwork. Lead time in Luxembourg City: 35 working days via Colt on-net. The density of Luxembourg's financial sector means most enterprise buildings are on-net or near-net.
Carriers, infrastructure and routing
POST Luxembourg is the national carrier — internet speeds up to 10Gbps, strong business services. Tango (a Proximus subsidiary) provides 5G and fibre services with competitive pricing. Colt is our primary recommendation for enterprise delivery in Luxembourg, with high-bandwidth SDN connectivity into Luxembourg's carrier-neutral data centres.
Luxembourg's data centres are genuinely carrier-neutral — with access to BT, Colt, Eurofiber, LuxNetwork, Proximus, Orange, Post, T-Systems, Tango, and Verizon available in the major facilities. Portus Data Centre in Cloche d'Or is 100% underground, carrier-neutral, 100% renewable — designed specifically for financial services and government data requiring the highest physical security standards.
LU-CIX is the national internet exchange, facilitating local traffic exchange and providing a strategic alternative peering point to \[Frankfurt\](/countries/germany), \[Amsterdam\](/countries/netherlands), and \[London\](/countries/uk). For financial services clients who already have presence in those cities, Luxembourg peering adds meaningful redundancy.
