STACK OSL03 Fetsund Data Center Campus

OSL03 is the four-building Fetsund campus historically totaling 22 MW. Current records still map the campus under STACK, while transaction evidence indicates at least one enterprise-colocation component entered the Apollo carve-out. The available public sources do not establish a single project-scoped capacity figure. The named capacity or identity conflict remains unresolved.

The legacy campus total is 22 MW across four buildings, but public M&A evidence indicates at least a colocation component entered the Apollo/Vaultica carve-out. The campus/operator boundary is unresolved and the headline is withheld.

Renewable hydroelectric power, embedded fiber and core infrastructure, and Nordic-climate air-to-air cooling.

Cooling and resilience architecture is described at facility or campus level; instantaneous draw and tenant utilization remain undisclosed.
