CoreSite questions
In our 25 tracked metros, CoreSite has facilities in 9: New York, Ashburn, Chicago, Los Angeles, Silicon Valley, Atlanta, Denver, Miami, Boston.
Put CoreSite in the same bid as the facilities around it. Every bid lands on one 36-month cost: rent, power model, cross-connects, escalators and SLA credit caps, so a low headline rate can't hide the rest.
Often, if the alternatives are real. Upload the renewal notice and we'll get competing bids before your notice deadline; the incumbent can match them or you can move. Renewal counter-quotes.
Make CoreSite compete
Send your spec or your CoreSite renewal notice. CoreSite and the facilities around it bid blind on the same 36-month basis.
- 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.
