The main interconnection buildings are Equinix Ashburn campus (21715 Filigree Ct, Ashburn, VA), CoreSite Reston VA1 (12100 Sunrise Valley Drive, Reston, VA 20191), Digital Realty IAD39 (44274 Round Table Plaza, Ashburn, VA 20147). Buildings with more networks on site mean shorter, cheaper cross-connects to the carriers and clouds you need.
The industrial electricity average is 10.07 cents/kWh (VA industrial). Facilities that bill power separately pass this through with their PUE on top, so ask each bidder for its billed PUE and power rate.
Providers bid blind: they see the technical spec only, never your name, email, phone or company, and never a file you upload. We introduce you only to the provider you pick. We ask at least three facilities to price your power, space and interconnection spec, put every quote on one 36-month landed cost, and reply within one business day.
