AI and Neocloud customers are bringing higher-density requirements into data centers that were not originally designed for these workloads. Customer needs can shift significantly within a short period, creating a challenge for operators trying to make existing infrastructure work harder without committing to unnecessary upgrades. The question is: How far can a facility be adapted before its existing design begins to limit what can be delivered?

Drawing on real examples from the NTT Global Data Centers EMEA portfolio, this facility tour dives deeper into the engineering decisions involved in preparing facilities like the Madrid 1 site for AI. It considers what can be achieved through retrofit, how the right approach differs from site to site, and what current projects can teach operators about preparing for the next generation of compute demand.
