The market is fragmented: unknown operators control 14 facilities, while Teraco leads with 11 sites and an unnamed operator runs 10, followed by Vantage Data Centers 4 and NTT 3. This fragmentation masks underlying infrastructure stress—the low excess-power score signals limited headroom for new workloads or growth, while the moderate-to-high constraint score reflects structural limitations in power delivery, cooling capacity, or grid reliability that directly impede operational expansion. For acquisition-focused investors, the DCPI verdict of AVOID is unambiguous. A constraint score of 55/100 means that even available power capacity cannot be…
