LOCKSS Global Network — $2,642-$13,222/yr + ~$700/yr per node; 27 years operational

LOCKSS Global Network membership runs $2,642-$13,222/year, scaled across 13 tiers determined by library materials budget and 6 geographical zones, with consortial and multi-year discounts available. Per-node hardware adds approximately $700/year, and the recommended storage envelope is 30-40 TB. Continuous operation since 1999 — twenty-seven years — makes LOCKSS the longest-running Tier 2 distributed preservation network of its kind.

The LOCKSS pricing structure reinforces the C-0030 pattern: proportional, scale-aware fees combined with low per-node hardware cost produce a deployment model that institutions can sustain across multi-decade horizons. The 27-year continuous-operation record is the longest of the Tier 2 consortia documented in this paper, and the survival pattern correlates with the proportional-fee economic structure rather than with the technology stack.
