Questions about CoreSite - Chicago (CH1)
PeeringDB lists 75 networks, 6 internet exchanges and 3 carriers at this facility (captured 2026-10-23). Every one of them is reachable with an in-building cross-connect.
Pricing is quoted per deal, so the honest answer comes from bids. As a benchmark, Retail full racks generally run $900 to $2,000 a month, and all-in pricing averages about $250 per kW per month (Inflect, 2026-04-01). Where power is metered, Chicago utility rates add about $85 per committed kW per month at 70% draw and a billed PUE of 1.4. Digital Realty's Q2 2026 filing reports $293/kW for new Americas contracts under 1 MW and $156/kW above 1 MW (Form 8-K): small footprints pay more per kW. GigeNET publishes Chicago list prices from $99 for 1U to $1,400 for a full rack (list prices, captured 2026-10-23).
