STACK MIL02A is the Via Marche 9 facility opened in July 2022. Current transaction and facility records suggest that the colocation asset may now sit within the adjacent Vaultica MIL01 campus boundary, but the public evidence does not provide a clean one-to-one successor mapping. The available evidence does not establish a clean one-to-one successor mapping, so the possible consolidation remains unresolved. The named capacity or identity conflict remains unresolved.
