AU-Aleutian

Overview

The AU-Aleutian is a domestic submarine cable system operating entirely within the state of Alaska, United States. Spanning 1,491 kilometers, it connects remote and geographically isolated communities along the Alaska Peninsula, the Kodiak Island archipelago, and the eastern Aleutian Islands chain. The cable provides critical communication infrastructure to these areas, many of which previously relied on limited satellite or wireless services. The system was designed to enhance connectivity in a region where terrestrial infrastructure is sparse or non-existent, addressing the unique challenges of Alaska's rugged and remote coastal geography. Operational since 2022, the AU-Aleutian is a vital link for residents and businesses in these communities, offering improved access to digital resources and communication networks.

Route and Landings

The AU-Aleutian cable system features fourteen landing points, all located in Alaska, United States. Its route is strategically designed to serve two primary geographic clusters: the Kodiak Island area and the Alaska Peninsula extending toward the Aleutian Islands. The cable's landings include Akutan, Chignik Bay, Chignik Lagoon, Chignik Lake, Cold Bay, False Pass, King Cove, Kodiak, Larsen Bay, Ouzinkie, Perryville, Port Lions, Sand Point, and Unalaska. These locations represent a mix of small towns and villages, many of which are inaccessible by road and rely on maritime or air transport for connectivity to the outside world.

The cable traverses some of the most challenging marine environments in the North Pacific, including waters near the Gulf of Alaska and the Bering Sea. These regions are known for their rough seas, strong currents, and seismic activity, making the deployment and maintenance of submarine cables particularly complex. The cable's route reflects a deliberate effort to connect isolated communities while navigating the geographic and environmental difficulties of the area.

Ownership and History

The AU-Aleutian submarine cable system is owned and operated by GCI Communication Corp, a telecommunications provider based in Alaska. GCI specializes in delivering connectivity solutions to underserved and remote regions across the state. The cable became ready for service in 2022, marking a significant milestone in Alaska's telecommunications infrastructure. Its deployment underscores GCI's commitment to extending high-speed internet and reliable communication services to some of the most remote areas in the United States.

The AU-Aleutian is part of a broader trend of regional submarine cable systems designed to address the specific needs of isolated communities. Unlike transoceanic cables that connect major population centers across continents, the AU-Aleutian focuses on providing dense, localized connectivity within a defined geographic area. This approach ensures that even the smallest and most remote communities in Alaska can benefit from modern communication technologies.

What Our Measurements Show

Our live monitoring of the AU-Aleutian cable system reveals performance metrics that reflect its role as a regional network. The cable is divided into 24 measured corridors, with the best round-trip time (RTT) recorded at 204 milliseconds and an average RTT of 254 milliseconds. These figures indicate a reliable and efficient system, particularly given the challenging environmental conditions and remote locations it serves.

The performance of the AU-Aleutian cable is crucial for the communities it connects, as it significantly improves access to digital services, including internet, telemedicine, and educational resources. By providing a stable and high-speed communication link, the cable plays a vital role in bridging the digital divide for residents of the Alaska Peninsula, Kodiak Island, and the Aleutian Islands. The data from our probes confirm that the AU-Aleutian is successfully fulfilling its mission of enhancing connectivity in this remote and rugged region.
