The city’s outstanding density of network carriers and direct cloud on-ramps provides the low-latency environment essential for driving revenue from financial services, gaming, and content delivery. This mature ecosystem ensures exceptional uptime and performance for any mission-critical application.

Seoul: At A Glance

Network & Connectivity Ecosystem

Seoul is one of Asia's most connected and carrier-dense markets, making it a primary hub for interconnection.

Carrier Density & Carrier Neutrality: With over 25 unique network providers, as of September 2025, Seoul offers a competitive landscape for connectivity. Businesses can access a rich mix of local, regional, and global carriers in the city's many carrier-neutral data centers, preventing vendor lock-in and optimizing transit costs.

Direct Cloud On-Ramps: The market features over 7 dedicated cloud on-ramps serving 5 distinct cloud regions, as of September 2025. This enables secure, high-throughput, low-latency private connections directly to major cloud providers, including Alibaba Cloud, AWS, Azure, and Oracle Cloud.

Internet Exchange Points (IXPs): The primary exchange is the Korea Internet Neutral Exchange (KINX). Peering at KINX allows networks to exchange domestic traffic efficiently, reducing latency and improving performance for end-users across South Korea.

Bare Metal: Bare metal cloud solutions are readily available in Seoul, providing dedicated compute resources for performance-sensitive workloads. Providers like Hivelocity and phoenixNAP offer dedicated servers in the region.

Power Analysis

Average Cost Of Power: Industrial power pricing in Seoul is approximately $0.13/kWh, as of October 2024. This rate is moderate compared to other major APAC hubs and is a key factor in the total cost of ownership for high-density compute deployments.

Power Grid Reliability: The power grid serving the Seoul metropolitan area is modern, well-engineered, and highly reliable. Major data center corridors are supported by redundant power feeds and multiple substations, ensuring high levels of uptime for critical facilities.

Market Access, Business & Tax Climate

Proximity To Key Business Districts: Data centers in the Seoul area provide low-latency connectivity to the city's major commercial hubs. These include the Gangnam Business District (GBD), the financial center at Yeouido (YBD), and the Central Business District (CBD), supporting finance, media, and technology firms.

Regional Market Reach: From Seoul, organizations can effectively serve the entire digitally-savvy population of South Korea. Its strategic location also makes it an excellent network node for reaching Japan, Taiwan, and parts of mainland China with minimal delay.

Tax Advantage For Data Centers: South Korea does not offer specific tax incentives for data center development or colocation customers. Businesses should anticipate the standard corporate tax environment and the 10% Value Added Tax (VAT) applied to digital infrastructure services.

Natural Disaster Risk

Seoul has a very low overall risk profile for natural disasters, with an INFORM Risk score of 2.1 out of 10, as of September 2025. While the aggregate risk is minimal, operators should engineer facilities to mitigate the region's most prominent hazards.

The highest individual risk factors are:

• Tropical Cyclone
• River Flood
• Coastal Flood
• Earthquake
