123NET Expands Southfield Data Center to Power AI and High-Density Deployments

SOUTHFIELD, Mich., Sept. 29, 2025 /PRNewswire/ -- 123NET, Michigan's premier carrier hotel and provider of data center and network services, has completed a major expansion of its Southfield DC1 Data Center, adding advanced colocation space and infrastructure tailored for the high-performance demands of AI inference and other data intensive applications.

The upgrades include a major 4-megawatt power expansion, creating Michigan's only facility where high-density GPU power with liquid and air-cooled infrastructure meets free on-site peering, enabling latency-sensitive workloads while cutting network costs by up to 70%. The data center optimization allows enterprises to deploy large-scale GPU infrastructure for real-time AI applications and machine learning at scale.

A key differentiator is the data center's on-premises Detroit Internet Exchange (DET-iX) switching fabric, which provides direct peering and fewer network hops for faster data exchange.

"Having DET-iX inside the data center gives our clients instant access to a powerful peering ecosystem and a more direct path to end users," said Dan Irvin, founder and CEO of 123NET. "It's the only place in Michigan where massive GPU power meets free peering, significantly cutting network costs compared to traditional colocation."

The DET-iX is one of the world's largest fee-free internet exchanges, serving 85 members, including Apple, Microsoft and Google, with traffic peaks exceeding 2.5 Tbps and port capacities up to 400 Gbps.

"We're seeing explosive demand for GPU clusters that require both substantial power and ultra-low latency," Irvin added. "This expansion, paired with our connectivity, creates an ideal environment for real-time AI workloads. We've built the density and network performance that serious GPU deployments require."
