Underground AI Data Centers: Bunkers, Mines, Mountains

Underground AI Data Centers: Bunkers, Mines, Mountains

Two narratives are converging: Silicon Valley’s rush to add gigawatts of AI capacity and a quiet revival of bunkers, mines, and mountains as ultra-resilient data hubs. Recent headlines point to unprecedented AI infrastructure spending tied to OpenAI. The draw is physical security, thermal stability, data sovereignty, and a narrative of longevity in an era where outages and cyber‑physical risks are rising. Geopolitics, regulation, and escalating outage impact are reshaping site selection and architectural choices. The AI build‑out collides with grid interconnection queues, water scarcity, and rising scrutiny of carbon and noise. Set hard thresholds on PUE and WUE; require real‑time telemetry and third‑party assurance.

Zayo and Equinix Launch an AI Infrastructure Blueprint

Zayo and Equinix launch an AI Infrastructure Blueprint
AI now depends as much on the network and interconnection layer as it does on GPUs, and this blueprint turns that reality into a repeatable design. Training has concentrated in a few massive regions, while inference is exploding at the edge and in enterprise colocation sites, creating a scale challenge the industry hasn’t codified until now. Zayo and Equinix are proposing a common model that aligns high-capacity transport, neutral interconnection hubs, and specialized training and inference data centers. The aim is to shorten time to market for AI services by providing reference designs that reduce trial-and-error across L1–L3, interconnection, and traffic engineering.

Databricks Integrates OpenAI GPT-5 in $100M AI Bet

Databricks Integrates OpenAI GPT-5 in 0M AI Bet
Databricks is adding OpenAI’s newest foundation models to its catalog for use via SQL or API, alongside previously introduced open-weight options gpt-oss 20B and 120B. Customers can now select, benchmark, and fine-tune OpenAI models directly where governed enterprise data already lives. The move raises the stakes in the race to make generative AI a first-class, governed workload inside data platforms rather than an external service tethered by integration and compliance gaps. For telecom and enterprise IT, it reduces friction for AI agents that must safely traverse customer, network, and operational data domains.

Spain is Telefónica’s showcase for fiber-led modernization. Dense FTTH has enabled a managed copper switch-off, which simplifies operations, cuts energy use, and improves service quality. The operator targets net zero by 2040 – ten years ahead of many international timelines—and reports a 52% reduction in CO2 emissions across the value chain from 2015 to 2024.

OpenAI, Oracle, SoftBank: 5 Stargate AI Data Centers

OpenAI, Oracle, SoftBank: 5 Stargate AI Data Centers
OpenAI plans five new US data centers under the Stargate umbrella, pushing the initiative’s planned capacity to nearly 7 gigawatts—roughly equivalent to several utility-scale power plants. Three sites—Shackelford County, Texas; Doña Ana County, New Mexico; and an undisclosed Midwest location—will be developed with Oracle following their previously disclosed agreement to add up to 4.5 GW of US capacity on top of the Abilene, Texas flagship. Two additional sites in Lordstown, Ohio and Milam County, Texas will be developed with SB Energy, SoftBank’s renewables and storage arm. OpenAI also expects to expand Abilene by approximately 600 MW, with the broader program claiming tens of thousands of onsite construction jobs, though ongoing operations will need far fewer staff once live.
