CoreSite alternatives, metro by metro
The best-connected buildings run by other operators wherever CoreSite operates. Use them to price a move, or to get a better renewal from CoreSite.
Networks, exchanges and carriers on site as listed in PeeringDB, captured 2026-10-23. Counts are self-reported by the networks and operators.
When to stay, when to switch
Stay when your deployment depends on networks only reachable in the building, when a move would cost more in migration and new cross-connects than the 36-month saving, or when the incumbent matches a real competing bid.
Switch, or at least bid it out, when the renewal notice raises rent or power faster than your workload grew, when you need more density than the building can commit in writing, or when your carriers are also present in a building next door.
A cross-connect from a nearby facility back to a carrier hotel is often cheaper than a cabinet inside it. Cross-connect costs · Migration checklist
Price the alternatives to CoreSite
Send your spec or the renewal notice you just received. At least three facilities that fit bid blind, and every bid comes back on one 36-month cost.
- Blind until you pick: facilities never see your name, email, company or files.
- Every bid on one basis: rent, power model, cross-connects, escalators and SLA credit caps.
- You sign direct with the facility. Participating providers pay our desk a placement commission when a buyer we introduce signs. It never changes their price or how we rank them.
