Ark data centers (Iowa): Green Bay Data Center

Ark’s Green Bay Data Center is located at W6149 Old Highway Road, Menasha (near Green Bay), Wisconsin. It occupies a 24.5-acre campus and was formerly part of Kimberly-Clark’s infrastructure before being acquired by Ark (formerly Involta). 

Because Green Bay is less congested and has lower utility rates than major hubs like Chicago, Ark claims ~40 % lower operational expense (OpEx) advantages for customers. 

The facility is designed as a concurrently maintainable (i.e. systems can be serviced without downtime) colocation site with expansion potential beyond 20 MW (and marketing materials note “up to 49 MW”) to support enterprise-scale infrastructure growth. 

⚙️ Facility Highlights

• Conditioned data center space: ~ 7,192 sq ft total, with ~5,000 sq ft of current colocation space 
• Raised floor: 30-inch raised floor for equipment 
• Power capacity (current/planned): marketing materials cite 3 MW current capacity with ability to scale beyond 49 MW in the campus build‐out 
• Redundant power architecture: 2N power redundancy claimed 
• Cooling systems: energy-efficient cooling infrastructure, N+1 planned cooling redundancy 
• Fire detection & suppression: specialized fire detection systems with reinforced concrete construction supporting robust safety 
• Campus expansion: multi-phased buildout adding further capacity (Ark broke ground on a 2 MW expansion phase in 2024)

🔐 Security & Compliance

• 24/7 secure access with biometric authentication and monitoring 
• Continuous remote monitoring / surveillance operations (NOC/SOC) 
• Carrier-neutral facility with multiple fiber paths, enabling interconnection flexibility (security is enforced at access points) 
• Certifications & compliance: the facility is marketed with compliance to HIPAA, HITRUST CSF, NIST 800-53, PCI DSS, SOC 1 Type 2, SOC 2 Type 2 
• Reinforced concrete construction and strong fire/structural resilience features 

🌐 Connectivity & Carrier Access

• Carrier-neutral environment: customers can choose from multiple network providers
• Redundant fiber entry paths: multiple diverse fiber ingress routes for resilience 
• Interconnection: onsite meet-me rooms and cross-connect services available 
• Network Operations Center (NOC) and secure connectivity management included as part of operational service 

💼 Who It Serves

• Enterprises and regional businesses seeking lower-cost colocation near Midwest U.S. markets
• Cloud service providers, SaaS and digital service companies needing scalable infrastructure in edge markets
• Healthcare, fintech, and regulated industries requiring compliance (HIPAA, PCI, etc.)
• Workloads needing resilient, redundant infrastructure but avoiding high cost in major hubs
• Organizations planning expansion over time, benefiting from the campus buildout potential
