Water utility cybersecurity lessons from 2026 alerts: OT exposure, remote access controls, incident reporting gaps, and resource limits.
AI performance risks after OpenAI’s isolation break show how sandbox failures, credentials, and agent behavior changed defensive assumptions.
Siemens S7 PLCs now face AI-assisted exploitation risk; here is a cautious, source-based look at exposure, limits, and OT defenses.
The Gemini AI cybersecurity incident is unsettling
The 10-Gigawatt Club: Only two states currently belong to this elite tier. While Virginia has reigned supreme for over a decade as the backbone of the internet, Texas is rapidly closing the gap. Fuelled by an independent grid and massive 1+ GW single-site campuses being built in the desert (like the Stargate initiative phases), Texas is on pace to eclipse Virginia entirely by the end of the decade.
The Rise of Arizona: Phoenix has officially bypassed Silicon Valley to become the third most powerful data center market in the US. Driven by massive investments from Microsoft and EdgeCore, Arizona’s capacity is projected to skyrocket as hyperscalers trade California’s strict regulations and high power costs for the desert’s stable, disaster-free environment.
The Nuclear Pivot in Pennsylvania: Notice Pennsylvania jumping into the top 10 despite having fewer total facilities than New Jersey or Florida. This is driven entirely by AWS’s massive acquisition and expansion of the Cumulus data center campus, which is directly powered by the 2.5 GW Susquehanna nuclear power plant.
The “Legacy” States: States like California, New Jersey, and New York still boast a high number of facilities, but their total GW output is stagnating. These are largely older, smaller colocation centers running at 10-20 MW, which pale in comparison to the 200-500 MW AI campuses currently being built in Ohio, Georgia, and Iowa.

Total Active IT Power Capacity refers to the amount of IT power currently deployed and supporting live AI, cloud, and enterprise workloads across operational facilities. As of the latest update, this figure stands at 39.0 GW.
There are currently 5,411 AI cloud and data center facilities operating across the United States. These facilities support hyperscale, enterprise cloud, and high-performance computing workloads.
This metric reflects 84 facilities scheduled to become operational within the next 90 days. It provides visibility into near-term expansion and immediate infrastructure growth.
There are 412 facilities currently under construction, representing confirmed development projects that will contribute to future IT power capacity.
Total Imminent Capacity represents IT power expected to be activated in the near term. This currently totals 1.2 GW of additional capacity nearing operational deployment.
Total Pipeline Capacity reflects the projected capacity across all planned and future development projects. The current pipeline stands at 35.0 GW, including facilities in planning, permitting, and early-stage development.
All infrastructure metrics are regularly updated to reflect the most current operational, construction, and development status available from verified sources.
