Castle IT Saint-Omer

Castle IT, a French operator whose main facility is in Larçay near Tours, is building a second data center in Saint-Omer in the Pas-de-Calais department of northern France. The announced scale is modest: about 200 square metres of space and 40 racks, against the 264 racks at Larçay. The company positions the site as a nearby second location for business continuity and backup, aimed at customers in the Hauts-de-France region who want a replica not too far from their primary installation. Development is split into two phases, with the first expected to open by the end of 2026. Castle IT has not published a power capacity, cooling design or certification level for Saint-Omer, so those fields are left empty here rather than inferred. The project is a useful marker of regional French colocation demand outside Paris and Marseille, where small sovereign-minded operators add edge-scale capacity close to enterprise users instead of competing for hyperscale megawatts.
