Earlier this year a ship hauled a large, barnacle-covered cylinder sporting a Microsoft logo from the seas off the Orkney islands. Inside were a dozen server racks, of the sort found in data-centres around the world. Sunk in 2018, and connected to the shore by cable, the computers had spent the past couple of years humming away, part of an experiment into the feasibility of building data-centres underwater.
On September 14th, 2020 Microsoft revealed some results. The aquatic data-centre suffered equipment failures at just one-eighth the rate of those built on land. Being inaccessible to humans, the firm could fill it with nitrogen instead of air, cutting down corrosion. The lack of human visitors also meant none of the bumping and jostling that can cause faults on land.
Microsoft hopes some of the lessons can be applied to existing, land-based data-centers. In the longer term, though, it notes that building underwater offers advantages beyond just reliability. Immersion in seawater helps with cooling, a big expense on land. Data-centres work best when placed close to customers. Land in New York or London is expensive, but nearby sea-floor is cheap. More than half the world’s population lives within 120 miles (192km) of the sea. Ben Cutler, the engineer in charge of the project, says submarine data-centres could be co-located with offshore wind farms as “anchor” customers. The cylinder fits in a standard shipping container, so could be deployed to remote places like islands, or even disaster areas to support relief efforts.
United States officials granted Google permission to turn on a high-speed internet link to Taiwan but not to the Chinese territory of Hong Kong, citing national-security concerns in a ruling that underscores fraying ties between Washington and Beijing.“There is a significant risk that the grant of a direct cable connection between the United States and Hong Kong would “pose an unacceptable risk to the national security and law enforcement interests of the United States,” the U.S. Department of Justice said in its decision, which was backed by the departments of Homeland Security and Defense. The agencies instead urged the Federal Communications Commission to grant Google owner Alphabet permission to start using the portion of its 8,000-mile underwater Pacific Light cable that connects California to Taiwan. .
The decision threatens to end Hong Kong’s dominance as a top destination for U.S. internet cables and puts at risk several ongoing projects, including a Facebook backed fiber-optic line linking Los Angeles to Hong Kong and a Google-backed project linking Hong Kong to the U.S. territory of Guam.
Washington is turning to the self-ruling island of Taiwan, which the U.S. supports with arms sales and unofficial political ties despite Beijing’s claims that it is part of China. U.S. officials are also considering alternatives such as Indonesia, Philippines, Thailand, and Vietnam.
Google and Facebook originally teamed up to build Pacific Light to Hong Kong in 2016, continuing the Silicon Valley giants’ long-term strategy to take more control of the network pipes that connect their data centers. The web companies and their Chinese investment partners kept building the cable even as U.S. authorities withheld the regulatory approvals they needed to start using it.
Major international data projects are subject to review by Team Telecom, a coalition of federal agencies with national-security oversight. The panel has taken a hard line against China in recent years. Team Telecom in 2018 recommended for the first time the denial of a Chinese application—that of China Mobile —to provide telecom services through U.S. networks, citing national-security and law-enforcement concerns.
President Trump on April 4 2020 signed an executive order that puts the attorney general in charge of overseeing Team Telecom and gives the panel direct authority to review existing licenses to provide such services, including those issued earlier to Chinese state-owned operators China Telecom and China Unicom.

A new front has opened in the battle between the U.S. and China over control of global networks that deliver the internet. This one is beneath the ocean. While the U.S. wages a high-profile campaign to exclude China’s Huawei Technologies Co. from next-generation mobile networks over fears of espionage, the company is embedding itself into undersea cable networks that ferry nearly all of the world’s internet data.
About 380 active submarine cables—bundles of fiber-optic lines that travel oceans on the seabed—carry about 95% of intercontinental voice and data traffic, making them critical for the economies and national security of most countries.
The Huawei Marine’s Undersea Cable Network majority owned by Huawei Technologies, has worked on some 90 projects to build or upgrade submarine cables around the world…US o fficials say the company’s knowledge of and access to undersea cables could allow China to attach devices that divert or monitor data traffic—or, in a conflict, to sever links to entire nations. Such interference could be done remotely, via Huawei network management software and other equipment at coastal landing stations, where submarine cables join land-based networks, these officials say.
Huawei Marine said in an email that no customer, industry player or government has directly raised security concerns about its products and operations.Joe Kelly, a Huawei spokesman, said the company is privately owned and has never been asked by any government to do anything that would jeopardize its customers or business. “If asked to do so,” he said, “we would refuse.”
The U.S. has sought to block Huawei from its own telecom infrastructure, including undersea cables, since at least 2012. American concerns about subsea links have since deepened—and spread to allies—as China moves to erode U.S. dominance of the world’s internet infrastructure…..Undersea cables are owned mainly by telecom operators and, in recent years, by such content providers as Facebook and Google. Smaller players rent bandwidth.Most users can’t control which cable systems carry their data between continents. A handful of switches typically route traffic along the path considered best, based on available capacity and agreements between cable operators.
In June 2017, Nick Warner, then head of Australia’s Secret Intelligence Service, traveled to the Solomon Islands, a strategically located South Pacific archipelago. His mission, according to people familiar with the visit, was to block a 2016 deal with Huawei Marine to build a 2,500-mile cable connecting Sydney to the Solomons. Mr. Warner told the Solomons’ prime minister the deal would give China a connection to Australia’s internet grid through a Sydney landing point, creating a cyber risk, these people said. Australia later announced it would finance the cable link and steered the contract to an Australian company. In another recent clash, the U.S., Australia and Japan tried unsuccessfully in September 2018 to quash an undersea-cable deal between Huawei Marine and Papua New Guinea.
U.S. and allied officials point to China’s record of cyber intrusions, growing Communist Party influence inside Chinese firms and a recent Chinese law requiring companies to assist intelligence operations. Landing stations are more exposed in poorer countries where cyber defenses tend to be weakest, U.S. and allied officials said. And network management systems are generally operated using computer servers at risk of cyber intrusion. Undersea cables are vulnerable, officials said, because large segments lie in international waters, where physical tampering can go undetected. At least one U.S. submarine can hack into seabed cables, defense experts said. In 2013, former National Security Agency contractor Edward Snowden alleged that Britain and the U.S. monitored submarine cable data. The U.S. and its allies now fear such tactics could be used against them. American and British military commanders warned recently that Russian submarines were operating near undersea cables. In 2018, the U.S. sanctioned a Russian company for supplying Russian spies with diving equipment to help tap seabed cables.
China seeks to build a Digital Silk Road, including undersea cables, terrestrial and satellite links, as part of its Belt and Road plan to finance a new global infrastructure network. Chinese government strategy papers on the Digital Silk Road cite the importance of undersea cables, as well as Huawei’s role in them. A research institute attached to China’s Ministry of Industry and Information Technology, in a paper published in September, praised Huawei’s technical prowess in undersea cable transmission and said China was poised to become “one of the world’s most important international submarine cable communication centers within a decade or two.” China’s foreign and technology ministries didn’t respond to requests for comment…
Bjarni Thorvardarson, then chief executive of the cable’s Ireland-based operator, said U.S. authorities raised no objections until 2012, when a congressional report declared Huawei Technologies a national security threat. Mr. Thorvardarson wasn’t convinced. “It was camouflaged as a security risk, but it was mostly about a preference for using U.S. technology,” he said. Under pressure, Mr. Thorvardarson dropped Huawei Marine from Project Express in 2013. The older cable network continued to use Huawei equipment.
The company is now the fourth-biggest player in an industry long dominated by U.S.-based SubCom and Finnish-owned Alcatel Submarine Networks. Japan’s NEC Corp is in third place.Huawei Marine is expected to complete 28 cables between 2015 and 2020—nearly a quarter of all those built globally—and it has upgraded many more, according to TeleGeography, a research company.
Excerpts from America’s Undersea Battle With China for Control of the Global Internet Grid , WSJ, Mar. 12, 2019
The ships that lay electronic cables across the ocean floor look like cargo vessels with a giant fishing reel on one end. They move ponderously across the open water, lowering insulated wire into shallow trenches in the seabed as they go. This low-tech process hasn’t changed much since 1866, when the SS Great Eastern laid the first reliable trans-Atlantic telegraph cable, capable of transmitting eight words per minute. These days, the cables are made of optical fiber, can carry 100 terabits of data or more in a second, and aren’t owned only by telephone companies.
Among the newcomers are a few of the world’s leading internet companies, which have concluded that, given the cost of renting bandwidth, they may as well make their own connections. Facebook and Microsoft have joined with Spanish broadband provider Telefónica to lay a private trans-Atlantic fiber cable known as Marea. The three companies will divide up the cable’s eight fiber strands, with Facebook and Microsoft each getting two. The project, slated to be completed by the end of 2017, marks the first time Facebook has taken an active role in building a cable, rather than investing in existing projects or routing data through pipes controlled by traditional carriers. Marea will be Microsoft’s second private cable; a trans-Pacific one is scheduled to come online in 2017.
In June 2016, Google said it had finished a data pipeline running from Oregon to Taiwan, and it has at least two more coming: one from the U.S. to Brazil; the other, a joint project with Facebook, will connect Los Angeles and Hong Kong. Amazon.com made its first cable investment in May, announcing plans for a link between Australia and New Zealand and the U.S. Worldwide, 33 cable projects worth an estimated $8.1 billion are scheduled to be online by 2018, according to TeleGeography. That’s up from $1.6 billion worth of cables in the previous three years. And bandwidth demand is expected to double every two years. ..
Cables are just one way to increase the supply of bandwidth and cut costs, says Chetan Sharma, an analyst and telecom consultant. Facebook is also working on satellites, lasers, and drones to deliver internet access to remote places, and Google has experimented with hot air balloons. So far, undersea cables remain the best option for crossing oceans—they’re cheaper, far more reliable, and largely unregulated.The United Nations treats ocean cables in much the same manner as boat traffic, meaning companies can lay and repair cables in international waters pretty much wherever they please, provided they don’t damage existing ones.So Silicon Valley will continue to pour money into technology pioneered in the telegraph era. “It’s about taking control of our destiny,” says Mark Russinovich, chief technology officer for Microsoft’s cloud services division, Azure. “We’re nowhere near being built out.”
