Initiative overview

Clarence is a Luxembourg sovereign cloud operated by a joint venture between LuxConnect and Proximus Luxembourg. It offers an air-gapped (“disconnected”) cloud—installed in LuxConnect Tier IV data centres in Luxembourg—that is locally managed and kept isolated from the internet and third parties, with the goal of ensuring EU-only jurisdiction, data residency, and operational sovereignty. The platform is built on Google’s Distributed Cloud Hosted technology (sovereign controls without external operator access) and targets government and regulated sectors needing confidential workloads, including AI.
