Chicago · The Loop & 350 E. Cermak · Since 1991

Your infrastructure.
Chicago solid.

Two downtown Chicago data centers connected by dark fiber. Fractional racks, flexible power, onShore ISP connectivity, and managed everything — from a single U to a private cage.

Everything you'd expect. Plus the things most providers charge extra for.

Every colocation tier comes with the infrastructure fundamentals. Connectivity, power, and management services are quoted to your actual requirements — no forced bundles, no one-size-fits-all tiers.

🏢

Monitored Around the Clock

Physical security monitoring, climate control, and video surveillance 24/7. A real human answers the phone at 3am — remote NOC always watching, on-call dispatch available when on-site response is needed.

Custom Power

We spec power to what you're actually running — from low-draw single-phase to high-density configurations. Generator-backed UPS at every tier. No forcing you into a standard circuit that doesn't fit your load.

🔒

Secure Cabinets & Access

Private locked cabinets for all dedicated tiers. 24/7 keyed access available. Remote hands included for tasks under 15 minutes — no charge for a cable swap or a quick reboot.

📡

onShore ISP + Any Carrier

onShore is a licensed ISP — we sell bandwidth directly, which simplifies your bill and your support call. We cross-connect any carrier you bring for redundancy. No obligation to buy our connectivity, but most customers do.

☁️

Cloud Interconnects

Direct private connections to AWS, Azure, and Google Cloud — designed, built, and managed by onShore engineers. Hybrid colo/cloud is the most cost-effective model for most mid-market workloads.

🌐

SD-WAN, DIA & Private Circuits

We integrate colo into your SD-WAN fabric and manage the full WAN — colo to edge. Includes DIA provisioning, private circuit ordering, and carrier management across all your sites.

The connectivity value of 350 E. Cermak — at a fraction of the price.

350 E. Cermak is one of the most interconnected buildings in the Midwest — and one of the most expensive places to colocate in Chicago. Our Loop data center connects to it by private dark fiber, so you get access to that same carrier ecosystem and interconnect fabric at roughly a quarter of the direct cost.

For disaster recovery, the math is even more compelling: primary production at the Loop, DR at Cermak — with near-zero, fixed-cost dark fiber transport between them. No MPLS quotes. No monthly replication surprises. Two downtown locations, one bill, one team.

Fixed-cost dark fiber transport. Sub-millisecond latency. No monthly circuit surprises.

You pay for what you need. Nothing more.

We don't force you into a bundle. Space, power, connectivity, and management are each quoted to your actual requirements. Here's how each component works — tell us what you're running and we'll build you an itemized number.

Space

From 1U to private cage or room

Fractional options most providers don't bother with. Start with exactly what you need.

  • Shared rack: 1U – 4U
  • Private ⅓ rack: 14U
  • Private ½ rack: 21U
  • Full rack: 42U
  • Private cage or dedicated room
Power

Specced to your actual load

No standard circuits forced on you. Power is designed around what you're running.

  • Shared or dedicated circuits
  • Single-phase standard or custom
  • High-density configurations available
  • Generator + UPS at every tier
Connectivity

ISP direct, or bring your own

onShore sells bandwidth directly. Bring any carrier for redundancy. BGP and custom routing where applicable.

  • Burstable or flat-rate bandwidth
  • DIA provisioning & management
  • Any carrier cross-connect
  • BGP / custom routing
  • Cloud interconnects (AWS, Azure, GCP)
Management

Add only what you need

Modular managed services — one team handles it all, no third-party handoffs.

  • Remote hands (15 min included)
  • 24/7 uptime & bandwidth monitoring
  • Upstream IDS / managed firewall
  • Managed servers & OS
  • SD-WAN & private circuit management

The part most colo providers leave to you.

Space and power are table stakes. The real cost and complexity in colocation is everything that touches the network — carriers, peering, DIA circuits, routing, cloud connections, remote site integration. We own all of it.

onShore engineers handle your carrier relationships, order and manage DIA and private circuits, troubleshoot outages, manage BGP peering, and keep your colo connected to every asset you have — cloud, branch, or remote worker. One team. One call when something breaks.

ISP + Multi-Carrier Peering

onShore is your ISP if you want us to be — or we cross-connect any carrier you bring. We manage BGP peering, redundancy, and failover across all upstreams. No vendor finger-pointing when something breaks.

DIA & Private Circuit Provisioning

We order, provision, and manage Dedicated Internet Access and private circuits on your behalf — at the colo and across all your other locations. One team handles procurement, installation, and ongoing support.

Cloud Interconnects & Hybrid Architecture

Direct private connections to AWS, Azure, and Google Cloud — designed, built, and managed by onShore. Hybrid colo/cloud is the most cost-effective model for most workloads, and we handle the complexity end to end.

We've kept Chicago businesses always on since 1991.

Most colo providers sell you a cabinet and hand you a cross-connect form. onShore is a managed infrastructure company that also owns data center space in Chicago's most connected corridors. The difference is what happens after move-in.

Our engineers are reachable. Problems get solved. And when you grow into needing managed SD-WAN, cloud interconnects, or security services — it's one call to the same team that already knows your infrastructure.
