Data Centers in Guam

Guam – Strategic Mid-Pacific Connectivity Hub

Executive Summary

Guam is a critical digital nexus for businesses operating across the Pacific. Its unique geographic position as a major submarine cable landing station provides a vital, low-latency bridge between North American and Asian markets, directly impacting application performance and network resilience for global operations.

Guam: At A Glance

Network & Connectivity Ecosystem

Guam’s primary value is its role as a central landing point for numerous trans-Pacific submarine cables. This makes it an essential interconnection point for traffic between continents.

Carrier Density & Carrier Neutrality: The market includes 5 data centers from at least 2 facility providers as of September 2025. Carrier density is high, concentrated around the island's submarine cable landing stations, offering access to many global Tier 1 networks.

Direct Cloud On-Ramps: Guam has no direct public cloud on-ramps as of September 2025. Secure, private connectivity to major cloud providers is achieved through dedicated network extensions to primary hubs in Asia or North America, such as Tokyo.

Internet Exchange Points (IXPs): The MARIIX (Marianas Internet Exchange) facilitates local traffic exchange, improving performance and reducing reliance on trans-Pacific hops for regional data.

Bare Metal: Bare metal services are available through local and regional colocation providers, offering dedicated compute for specialized workloads that require physical proximity to the network edge in the Pacific.

Power Analysis

Average Cost Of Power: Industrial power is priced at approximately $0.14/kWh as of 2020. This rate is higher than in many continental US markets but is competitive for a strategic island location with significant subsea cable infrastructure.

Power Grid Reliability: The local power grid is isolated and relies primarily on fossil fuels. Data centers in Guam mitigate this with significant on-site N+1 or 2N redundant power infrastructure, including UPS systems and diesel generators, to ensure high uptime.

Market Access, Business & Tax Climate

Proximity To Key Business Districts: Data centers are strategically located to serve the U.S. military presence and the island's key submarine cable landing stations, which are the primary economic drivers for digital infrastructure.

Regional Market Reach: Guam provides a unique mid-point to serve markets across Oceania, East Asia, and the West Coast of the United States with improved latency. It acts as a crucial bridge for content delivery, financial services, and enterprise networks.

Tax Advantage For Data Centers: Guam offers specific tax advantages, including programs aimed at encouraging energy efficiency for commercial operations. These incentives can lower the total cost of ownership for data center deployments by reducing operational expenditures.

Natural Disaster Risk

Guam's geographic location presents a Moderate risk profile for natural disasters as of September 2025. Data center facilities on the island are typically engineered to withstand these specific regional threats.

Key environmental risks include:

• Typhoon: The island is in a region with a high frequency of powerful typhoons.
• Earthquake: The location within the Pacific Ring of Fire results in a higher potential for seismic activity.
• Tsunami: A potential risk due to seismic events in the Pacific Ocean.
• Flooding: Primarily a result of typhoon-related storm surge and heavy rainfall.
