Why it matters
Power delivery and cooling, rather than raw silicon availability, have become the primary constraints limiting the expansion of hyperscale AI data centers. A shift toward higher-voltage DC power architectures requires significant redesigns of facility infrastructure, power distribution units, and rack-level components. This transition impacts data center operators, utility planners, and server manufacturers who must redesign facility electrical topologies to handle escalating per-rack power densities without prohibitive energy losses.
Coverage
Primary/vendor sources vs independent reporting
Primary / vendor source: information published directly by the company, organization, government body or project involved. Useful as a primary source, but not independent confirmation.
Independent reporting: reporting or analysis from a source independent of the organization making the underlying claim.

Salesforce Customers Brace For New Fees to Use Claude in Its Apps
Salesforce plans to require enterprise customers to register external AI agents, such as Anthropic's Claude, beginning as early as next month, according to The Information. The registration process serves as an initial step toward charging fees whenever third-party AI agents update or analyze data stored inside Salesforce apps, allowing the vendor to monetize users who deploy external AI rather than its proprietary tools.
