Server idle capacity — only 40% of data centers measure utilization; 25% of physical servers comatose; 12-18% typical

The empirical base for "more than half of institutional server capacity sits idle" comes from four converging studies:

• Uptime Institute Global Data Center Survey (2023, 2024, 2025): only 40% of data center operators measured server utilization in 2023; 41% tracked it as a sustainability metric in 2024.
• Anthesis/Stanford ("Zombie/Comatose Servers Redux," 2015 with 2017 update): 30% of enterprise servers comatose in 2015; ~25% of physical servers and ~30% of virtual machines comatose in 2017 — running and drawing power while performing no work.
• NRDC Issue Paper IP:14-08-A (Whitney & Delforge, 2014): typical on-premises enterprise servers run at 12-18% of capacity where utilization is measured at all.
• LBNL 2024 United States Data Center Energy Usage Report: industry-wide modeling assumes 70% average utilization with substantial uncertainty, dominated by hyperscale rather than institutional infrastructure.

The implication for C-0006: institutional servers carry zero structural resilience for the data they hold, because none of the idle capacity is structurally connected to the preservation of that data. Adding a Tier 3 daemon to an enterprise server running at 15% utilization is invisible in the noise floor — the marginal cost of protocol-level participation on existing infrastructure is effectively zero.
