Telehouse: Telehouse THM1 Data Center

Telehouse THM1, operated by KDDI’s Telehouse (Telehouse France), is located at 71 Avenue André Roussin, 13016 Marseille, France. Strategically sited within a non‑flood zone, the facility benefits from a clear height under slab exceeding 3.50 m, accommodating racks up to 52U. Its location in Marseille—a globally recognized connectivity hub and entry point for numerous submarine cables—positions it as a critical gateway for traffic between Europe, Africa, the Middle East, and Asia, while also strengthening the digital corridor to Telehouse’s Paris TH2 campus.
