Johnstone Point, AK: A Remote Link in Alaska's Connectivity Chain

Johnstone Point, Alaska, may not be a household name in the world of submarine cables, but its role in regional connectivity is quietly significant. Located in a remote area of the United States, this landing point hosts the FISH West cable, a relatively short 276 km domestic line set to be ready for service in 2027. While many landing points in the United States are hubs for multiple international cables, Johnstone Point stands out as part of a smaller, localized network serving Alaska's coastal communities.

The FISH West Cable: Stitching Coastal Alaska Together

The FISH West cable connects Johnstone Point to three other landing points in Alaska: Chenega, Cordova, and Seward. This chain is designed to improve connectivity along the rugged and often isolated Alaskan coastline. Unlike major hubs such as Boca Raton, FL, or San Juan, PR-each hosting eight cables-Johnstone Point is part of a more modest infrastructure network. With just one cable landing here, it ranks in the top 69% of U.S. landing points by cable count, highlighting its niche role in the broader system. The cable does not extend internationally, focusing instead on domestic connections. This localized approach is essential for Alaska, where vast distances and challenging terrain make reliable communication networks a necessity for both residents and industries. The FISH West cable will likely enhance internet speeds, reduce latency, and support essential services for these coastal communities.

Latency Observations: A Unique GeoCables Insight

GeoCables' latency monitoring provides a rare glimpse into the performance of this landing point. Across 15 completed checks from 11 source cities, the average round-trip latency to Johnstone Point is 180 ms, with the best observed latency being 132 ms. These numbers reflect the challenges of connecting remote areas, where latency tends to be higher compared to urban hubs with dense cable networks. Nonetheless, these measurements are promising for a location serving such an isolated region.

Regional Context: A Small Player in a Big System

The United States boasts an extensive submarine cable infrastructure, with 113 cables landing across 160 points nationwide. Most landing points host multiple cables, with prominent hubs like Hermosa Beach, CA, and Kapolei, HI, supporting five cables each. In comparison, Johnstone Point's single cable underscores its specialized role in Alaska's connectivity rather than acting as a major node in the national or international network.

Why Johnstone Point Matters

While Johnstone Point may lack the scale and prominence of larger landing points, its importance lies in its ability to connect remote Alaskan communities. The FISH West cable will serve as a lifeline for these areas, ensuring they remain linked to the broader digital world. For a state where isolation is often the norm, this modest landing point plays a key role in bridging the gap between rugged landscapes and modern connectivity.
