Iron Mountain LON-2

LON-2 is the greenfield centerpiece of Iron Mountain's London campus, built specifically for hyperscale-scale requirements alongside the converted former-bank LON-1 building and the newer LON-3 under construction. At 27 MW it is the largest of the campus's operating buildings, and together the three facilities give Iron Mountain roughly 61 MW and 40,200+ square meters of colocation space in the London market once LON-3 completes. The operator applies its standard compliance stack across the campus — ISO 27001, ISO 9001, ISO 14001, ISO 22301, HITRUST, PCI-DSS, SOC 2 Type II and SOC 3 — though it does not break out a Tier rating, opening year or cooling-plant details specific to LON-2 on its facility page. London remains one of the tightest power markets in Europe, and Iron Mountain's decision to build new hyperscale-class capacity there, rather than relying solely on the converted LON-1 building, reflects the wider push by colocation operators to secure grid connections in the metro while they are still available.
