Subsea Cables & Internet Infrastructure

The planned Bulikala cable connects Google's modular prefabricated Guam CLS to Fiji. The branch is right below Guam on the map at the bottom of this page. It is part of a large scale Google project costing a billion dollars  to dramatically increase Pacific subsea throughput and resiliency via a web of island hopping fibre optic cables. These small islands such as Fiji, Christmas Island, the Marshalls, and Polynesia offer diverse network routing that is particularly valuable in case of a subsea cable segment goes dark. They also offer power, which is the gating factor for throughput over long distances. All power conductors lead to voltage drawdown which limits bandwidth. Boosting power at intermediate points will allow higher transmission rates and lead to better return on the capital invested. The overall plan is to connect Japan, Guam, Hawaii, many islands such as Fiji and French Polynesia to the US in such a way as to increase both throughput via power stops at small islands a...

This new subsea cable perfectly illustrates how these undersea digital highways have become instruments of political power and foreign policy. The Chinese government is lending the Cambodian government the money required to build a subsea cable that China Uncom will operate for Cambodia and which Hauwei Marine will undoubtedly build. Since it goes to Hong Kong China will probably tap the cable and record the bits traversing it. Now encryption protects the data payload, but not the header routing information. So the IP addresses can be captured and much can be deduced from them. Unfortunately, few details are available regarding the new network. The Chinese government clearly wants to be able to monitor and capture the region's data flows so subsidizing cables to land in China and to be built by Hauwei is in their eyes is simply prudent national security policy.
