KT Cloud Data Centers: Cheonan Data Center

The KT Cloud Cheonan Data Center is located in Cheonan, in South Chungcheong Province, South Korea. KT Cloud operates multiple cloud zones in Cheonan as part of its national IDC footprint. 

As part of KT’s strategy to expand cloud and data infrastructure, the Cheonan site supports both regional and national connectivity with proximity to major transport and power infrastructure. The facility is integral to KT’s efforts to build scalable, energy-aware data center capacity to serve public and enterprise customers across Korea. 

⚙️ Facility Highlights

• Cooling design: KT has promoted operating the Cheonan facility at higher ambient temperatures (e.g. up to ~86 °F / ~30 °C) to improve energy efficiency beyond standard practice, reducing cooling load. 
• Modular construction and expansion: KT uses modular expansion models for its data centers, which is one method employed for its Cheonan expansion work. 
• Infrastructure redundancy: the design targets include N+N primary & secondary distribution, and modular generator schemes to support maintainable operations.
• Diverse fiber and connectivity planning to provide resilient network paths. 

🔐 Security & Compliance

• While I did not find public documentation of specific security certifications (e.g. ISO, SOC) for Cheonan, KT Cloud in general positions its data centers to meet industry security and compliance norms
• Physical security is standard for major IDC operations (24/7 monitoring, restricted access), though explicit details for Cheonan were not publicly disclosed.
• Continuous operations oversight and facility monitoring are implied by KT’s cloud / IDC framework. 

🌐 Connectivity & Carrier Access

• Carrier-neutral or multi-carrier access: KT Cloud maintains its own backbone and connects its data centers with internal and external network providers. 
• High-speed connectivity to KT’s broader telecom and cloud network platforms, enabling low-latency paths within Korea. 
• Redundant fiber entry and diverse routing to reduce risk of single points of failure. 

💼 Who It Serves

• Korean enterprises needing regional colocation, cloud or hybrid infrastructure support
• Public sector agencies in South Korea requiring secure and locally hosted services
• Cloud, SaaS, or platform providers needing connectivity into KT’s domestic network
• Applications with high redundancy or distributed architecture needs across Korea
• Clients seeking energy-efficient operations (via higher temperature operation)
