About STACK OSL04 Holtskogen Data Center Campus

STACK OSL04 is the Holtskogen campus east of Oslo, independently registered at 18 MW across multiple facilities and marketed with certified renewable supply. It remains separate from the Oslo colocation assets rebranded as Vaultica, and the profile does not infer that the carve-out changed OSL04 ownership. Customer utilization, private contract terms and unreported project financing remain outside the verified public record.
