MIL11 is the largest of STACK's eleven disclosed Milan-area campuses — a portfolio that ranges from MIL03's 5 MW single building up to this 88 MW, two-building campus on 33 acres. STACK's page places MIL11 within easy reach of Milan's central district without giving a specific municipality or street address, consistent with how the operator discloses most of its Italian sites. The larger of the two buildings, MIL11A, is sized at roughly 688,460 sq ft (about 64,000 sqm) for 72 MW, with the smaller MIL11B contributing 16 MW across 360,160 sq ft (about 33,000 sqm). No Uptime Tier, ISO certification, cooling design, renewable-power claim or year-opened date is published for the site, unlike some of STACK's smaller Milan campuses (MIL02, MIL03, MIL08) that do advertise renewable sourcing.
