• 2026-09-15 Meta to expand Eagle Mountain data center campus in Utah · Data Center Dynamics
  Meta's fourth expansion of its Eagle Mountain, Utah campus pushes its investment there past $3 billion, adding self-built capacity outside the HPL-measured world this site otherwise tracks -- the same disclosed-versus-undisclosed distinction that motivates the shadow-list page. The new buildings will use closed-loop liquid cooling with dry cooling, a facility detail worth watching as more hyperscaler capacity shifts away from air.
• 2026-09-09 Panmnesia and Meta propose extending cache-coherent CXL beyond the rack to datacenter scale · HPCwire
  Every interconnect row in this dataset describes a fabric that either stops at the rack or treats cross-rack traffic as a network hop; the proposal here is to hold one cache-coherent domain across a whole facility, which would turn that boundary from a given into a design choice. It is an invited review article with components claimed as validated silicon but no deployed system behind it, so nothing in it belongs in the parts layer yet.
• 2026-04-15 Louisiana regulators fast-track review of seven more gas plants for Meta's Hyperion campus · Union of Concerned Scientists
  Ten gas fired units totaling roughly 7.5 gigawatts, up from three approved in August 2025, would power a single Meta data center at a scale that a critic notes exceeds six times New Orleans' peak demand. It is a sharp illustration of the recurring finding elsewhere in this dataset that grid power, not chip supply, has become the binding constraint on gigawatt class AI campuses like Hyperion.

  Vistra's contribution includes uprates at its existing Perry and Davis-Besse reactors, an operating asset route to new capacity that is faster than the Oklo and TerraPower agreements, which depend on advanced reactor designs not expected online before 2030 and 2032 respectively. Meta's Prometheus campus in Ohio, already in this dataset, is named as one beneficiary, though only a fraction of the contracted capacity is available on any timeline that matches Prometheus's 2026 target.
