On Net, 

Near Net Routes

Whether you’re co-locating, scaling across data centers, or building out edge infrastructure, Crosstown Fiber connects you to what matters—reliably, securely, and efficiently. Our On Net and Near Net routes serve as the backbone for some of the region’s most critical data corridors, offering diverse, subsurface paths engineered for performance and built for growth.

What Are On Net & Near Net Routes?

What Are On Net & Near Net Routes?

On Net

On Net locations are facilities where Crosstown Fiber already has direct infrastructure in place, enabling fast, cost-effective connectivity without construction delays.

Near Net

Near Net routes are facilities where Crosstown’s network passes nearby or can be rapidly extended, offering high availability with minimal deployment time.

Together, these routes form a resilient, low-latency mesh across the Chicago metro and surrounding Midwest, connecting the region’s most important data centers.

Extensive On Net Data Center Coverage

We’ve designed and deployed direct underground fiber infrastructure to dozens of key data centers. These include facilities operated by Equinix, Digital Realty, Coresite, Stack, ServerFarm, NTT, QTS, and more. From downtown Chicago to the Elk Grove Village corridor, our On Net footprint delivers the redundancy, speed, and security mission-critical applications require.

Why Crosstown Fiber’s Data Center Interconnectivity Stands Apart

Crosstown Fiber offers a high-performance, highly resilient data center interconnect network designed for the demanding needs of enterprise, finance, cloud, and hyperscale users. What makes our network special isn’t just where we go — it’s how we get there.

Strategic Locations with Purpose-Built Design

We don’t just connect to the region’s most important data centers — we do so in ways that optimize performance, security, and redundancy. Our routes are engineered with precision to reduce latency, simplify expansions, and deliver ultimate path diversity. Here are a few standout examples:

Equinix CH3

1905 Lunt
equinix-ch3
  • Planned South entrance will offer exclusive access.
  • Subsurface construction delivers enhanced physical security and fewer environmental disruptions.
  • Ideal for AI / Cloud, trading firms and edge compute requiring robust, hidden, and diverse pathways.

CoreSite CH1

427 S LaSalle
CoreSite-CH1
  • Three separate entrances to the building — ensuring physical path diversity.
  • Includes a rare East Point of Entry, giving unmatched flexibility for customers needing route separation.
  • Multiple high-capacity duct systems ready to scale with bandwidth-intensive use cases.

QTS Chicago

2800 S Ashland
QTS-Chicago
  • Only provider with entrance routing northbound on Damen Avenue across the Chicago River
  • This exclusive entry path ensures route diversity in a congested fiber corridor, minimizing cross-provider risk.
  • Ideal for clients needing customized routing and risk mitigation.

Equinix CH1/CH2/CH4

350 E Cermak
Equinix-CH1-CH2-CH4
  • Direct connectivity up to the 5th floor — one of the few fiber networks that can make this claim.
  • Supports seamless vertical integration for multi-floor tenants.
  • Eliminates the need for intermediate cross-connects, reducing cost and latency.
