Compare downtown and suburban facilities
Procuring Chicago colocation requires separating regional market labels from physical municipal locations. Buyers must assess whether a specific downtown building or suburban campus matches their required deployment footprint, cabinet counts and carrier access.
Facility address listings illustrate this geographic spread:
- CoreSite CH1 is listed at 427 S. LaSalle St., Chicago, IL 60605.
- CoreSite CH2 is listed at 1432 S. Clinton St., Chicago, IL 60607.
- DataBank ORD3 is listed at 800 E. Business Center Drive, Mount Prospect, IL 60056.
- DataBank ORD4 is listed at 1808 Swift Drive Suite B & C, Oak Brook, IL 60523.
A suburban address in Mount Prospect or Oak Brook requires comparing actual transit routes, carrier options and service delivery against measured latency requirements. A street address alone proves none of these factors.
Check the actual cloud connection path
Colocation proposals frequently highlight cloud access, but physical network topologies differ between buildings. Buyers must verify how cloud connectivity is provisioned and whether traffic remains within the facility or requires metropolitan backhaul.
Public records for AWS Direct Connect locations list CoreSite CH1 in Chicago as a direct access location, noting accessibility from CoreSite CH2. Technical delivery depends on customer placement:
- For customer equipment in a Direct Connect location, AWS documentation specifies completing a cross connect with the facility provider.
- For equipment outside a Direct Connect location, AWS outlines working with members of the AWS Partner Network (APN) to connect to the facility.
Buyers should ask whether an on-site cross-connect is offered directly or if partner-assisted transport links the deployment to the cloud point of presence. Confirming demarcation boundaries and bandwidth commitments before contracting avoids ambiguity.
Specify power, cooling and commercial terms
Evaluating Chicago colocation proposals requires checking facility capabilities against operational needs:
- Power commitments: Confirm day-one provisioned power against contracted IT load, verifying redundant feeds, breaker sizing and continuous power draw per rack.
- Thermal management: Align rack heat dissipation with installed cooling capacity, reviewing airflow containment and evaluating liquid cooling infrastructure for dense compute.
- Physical scope: Check whether space is allocated as cabinets, caged areas or private suites, alongside physical security and remote hands coverage.
- Service levels: Validate Service Level Agreements covering power uptime, support response windows and itemised cross-connect charges.
- Commercial structure: Review installation fees alongside recurring space and power commitments. For market context, examine standard colocation pricing models.
- Delivery timelines: Confirm phased expansion options and contractually binding operational delivery dates.
Get advice on a Chicago colocation requirement
Data Centre Axis provides data centre consultancy and advisory for sites, capacity, capital and transactions. Our team conducts an initial review of your requirement and commercial evidence. Colocation, wholesale and AI-ready capacity requirements are matched to facilities manually, followed by direct introductions to operators where both parties agree.
Where required, Data Centre Axis delivers individually scoped advisory support and introduces specialist consultants for technical, planning and legal requirements. Requirements may initially be discussed with potential counterparties in a non-identifying format. Personal and identifying contact details are shared only after the submitter explicitly agrees to the introduction. Commercial negotiations and contracts remain between buyer and operator.
Chicago colocation questions
Does a Chicago market label identify the building?
No. A Chicago market label often spans downtown facilities and suburban municipalities such as Mount Prospect or Oak Brook. Buyers should confirm the exact building and separately check proximity, offered connections and technical capability against their needs.
What should the initial requirement include?
Initial intake requires a non-sensitive outline: target country, metropolitan market, required power scale and planned operational date. Submissions can also note suburban preferences, rack densities and essential carriers. Sensitive documents are not required for preliminary review. See our privacy policy for data handling standards.
