About
CoreSite's CH1 data center occupies 180,000 square feet at 427 S. LaSalle St. in downtown Chicago, delivering mission-critical colocation infrastructure directly adjacent to the Chicago Board of Trade. For facility managers and property owners evaluating colocation or interconnection for their commercial operations, CH1 offers a rare combination of downtown density and enterprise-grade electrical resiliency: the facility is fed by multiple utility substations through an underground network configuration, substantially reducing single-point-of-failure risk that above-grade utility feeds cannot match. This power architecture is particularly relevant for tenants in Chicago's office, institutional, healthcare, and government sectors who require continuous uptime for critical workloads. The facility's electrical and mechanical infrastructure is engineered to support a full range of deployment scales, from individual colocation cabinets and private cages to large private suites, making it appropriate for mixed-use commercial tenants scaling IT infrastructure without capital investment in owned data center buildout. On the interconnection side, CH1 provides direct cloud on-ramps to AWS, Microsoft Azure, Google Cloud, and Oracle FastConnect, plus access to CoreSite's proprietary Open Cloud Exchange, enabling low-latency multicloud connectivity for Chicago-area businesses. The facility operates with 24x7x365 staffing across security, field operations, and remote hands — a staffing model that mirrors the service expectations facility managers impose on their own critical building systems. CoreSite's broader 11-market footprint means multi-site coverage is available for organizations with distributed facilities across major U.S. metros. For facility and property managers benchmarking colocation providers in the Chicago market, CH1's underground utility feed redundancy, carrier-dense interconnection ecosystem, and scalable power and space options represent a well-documented, commercially substantiated value proposition.
