CoreSite CH1 — Top 10 data centers in Chicago, United States 2026
#6 of 16 · See the list →

CH1 occupies 427 S. LaSalle Street in downtown Chicago, placing colocation capacity directly in the Loop rather than in the suburban clusters west of the city. The facility spans more than 180,000 sq ft and serves as the network hub of CoreSite's Chicago footprint, sitting two miles from the newer CH2 building. Its differentiator is connectivity: over 60 networks are available on site, alongside native cloud on-ramps to AWS, Microsoft Azure, Google Cloud and Oracle, plus the CoreSite Any2Exchange, AMS-IX Chicago, DE-CIX and United IX peering platforms, a combination that also serves Chicago's low-latency trading community. Power infrastructure supports N, N+1 and 2N redundancy options on UPS and distribution, backed by a 100 percent uptime SLA with 24x7 on-site security and field operations. Compliance covers SOC 1 and SOC 2 Type 2, ISO 27001, PCI DSS, HIPAA and NIST 800-53. CH1 fits enterprises, financial firms and network operators that value interconnection density over megawatt scale.
