DEEP (A POST Luxembourg Company): Lille Data Center

The Lille Data Center, operated by DEEP (a POST Luxembourg Group entity combining EBRC, Elgon, Digora, and POST Telecom), is positioned to bridge France and Luxembourg with sovereign-grade infrastructure. Though DEEP’s core data center footprint is centered in Luxembourg, their network extends into the neighboring French region; the Lille location offers strategic access to the French market and cross-border connectivity.

Its location advantage includes proximity to major Northern French metro hubs (e.g. Paris, Brussels, Frankfurt) and fiber backbone nodes, enabling low-latency paths into Luxembourg and the broader Benelux region. The Lille site supports DEEP’s ambition to provide a sovereign, high-availability alternative to hyperscale cloud providers in Europe.
