DE1 is the Denver Gas and Electric Building, raised in 1910 in the Chicago School style and once outlined by 13,000 electric bulbs, on the National Register of Historic Places since 1978. CoreSite had leased space here for years and bought the building outright on 8 April 2025, taking on roughly a hundred additional interconnection customers and planning about 3 MW of new capacity. It is the most network-dense address in the Rocky Mountain region: 147 networks and three exchanges are on-net across 152,000-plus square feet, and CoreSite hosts its Any2Denver peering fabric here. Generators run N+1 with N and 2N options across UPS, PDU and RPP. A Google Cloud on-ramp is available on site, and dark fiber runs to DE2 a mile away.
