Lumen Dallas 4 — 400 South Akard Colocation Footprint

Lumen Dallas 4 should be modeled as an address-level service footprint inside the multi-tenant 400 South Akard building. The facility profile lists 36,219 square feet of total space and 6,479 square feet of dedicated colocation space, plus AC UPS and DC configurations, generator and battery backup, N+1 HVAC, diverse fiber, backhaul, and Level 3 network services under Lumen’s Premier framework. The profile records the predecessor path from Level 3 to CenturyLink and then Lumen.

DataBank’s current DFW1 page independently identifies 400 South Akard as its downtown Dallas data center in the former Federal Reserve building. DataBank publishes 145,250 IT square feet, a 7 MW critical IT load, 2N power design, N+1 cooling, and a carrier-hotel role. Lumen’s current wavelength site list also includes 400 South Akard. These sources support a parent/child relationship and current network relevance, but they do not disclose Lumen Dallas 4’s own MW allocation, occupancy, or contract inventory.

The suite/building distinction answers the query first. DataBank DFW1’s 7 MW remains a parent-building figure, not a Lumen allocation or availability claim. This record links to DataBank DFW1, Fidium’s historical/brand record, and other 400 South Akard occupants while keeping each operator identity separate. Any commercial inquiry should request Lumen-specific space and power confirmation.
