Taiwan worried about threat of China sabotaging undersea Internet wires

Matsu [Taiwan], March 11 : The undersea internet cables serve the Matsu island chain, part of Taiwan, but at points, which are only a few miles from China, internet outage is not unusual. The cause of Matsu's internet outage is familiar: Chinese fishing boats, so omnipresent that the nightly glow of their green lights has become known as the islands' own aurora borealis, the Washington Post reported.
Wayward anchors and trawling nets have taken out the islands' two internet cables 27 times in the past five years. But this is the first time Matsu has faced such a long outage, as one of the world's few dozen repair ships won't be available to fix the breaks until the end of April.
The first cable was damaged on February 2 by a Chinese fishing boat and the second, on Feb 8 by a Chinese cargo ship, according to Taiwanese authorities, the Washington Post reported.
This plunged residents back in time and forced them to confront what life would be like if increasing tensions with China made Taiwan's internet infrastructure an intentional target.

Tensions have flared in recent months following US House Speaker Nancy Pelosi's visit to Taipei in August.
Taiwan's military maintains a major presence in Matsu. On a recent night people in fatigue jogged around Nangan harbour and played basketball outside the Matsu islands' only Coffee shop.
There is no evidence that the cables were severed intentionally, according to Chunghwa Telecom. But analysts and local officials have said the frequent cable breaks caused by Chinese vessels amount to purposeful harassment that keeps Taiwan's government and telecom companies scrambling to provide basic services.
"What happened in Matsu can be seen as a warning signal," said Wen Lii, the head of the local chapter of Taiwan's ruling Democratic Progressive Party (DPP).
"If an internet outage could happen for Matsu, the same thing could happen for Taiwan, what would we do if Taiwan's 14 international undersea cables were damaged?" Lii added.
The Matsu island chain was on the front line of fighting during the Chinese civil war in the 1940s and its closest island is just six miles off the coast of China's Fujian province. The islands, home to about 14,000 people, depend heavily on tourists drawn to the quiet, once heavily fortified beaches where bunkers have become hip cafes and guesthouses.
But without the internet, businesses have slowed to a trickle. Half a dozen hotel and restaurant owners said that the ongoing outage meant their business was down at least 50 per cent compared with the same time last year, Washington Post reported.
"At its worst point, the phone barely rang at all, and the calls that did get through were full of noise," said Wang Yuan-song, who owns a hotel near the airport on Beigan, one of the Matsu islands. "There was no way to communicate normally."
After a shorter outage put his business on hold last April, Wang was prepared for this one. He had friends on Taiwan's main island send him prepaid mobile SIM cards, then put the cards into his own internet routers to make shareable WiFi hotspots for guests. The weak signal was barely usable but better than nothing, he said.
Chunghwa Telecom has set up a high-powered microwave radio transmission from towers near Taipei to provide a backup signal for online banking and other basic services for Matsu residents, but the service is intermittent and slows to a crawl during peak use.
Chinese military ships, fishing vessels and sand dredgers regularly cross into Taiwan's waters using what military analysts describe as grey-zone tactics -- part intimidation campaign, part resource extraction -- intended to keep Taiwan's people and government on alert.
The Chinese Communist Party government shelled Matsu for decades after the nationalist Kuomintang (KMT) government retreated to Taiwan in defeat in 1949, and gained control of some of the outlying islands that are much closer to China than Taiwan.
In doing so, they drew an invisible boundary across previously free-flowing fishing grounds. Matsu's rocky coastline, lined with the same type of stone houses built in Fujian, was fortified with land mines.
But China's proximity is not just a threat for Matsu residents -- for many, their neighbour is also a source of practical solutions. During the most acute parts of the outage, some Matsu residents stayed online using SIM cards from China.
Some locals found ways to get SIM cards from China and connect to cell signals from inside the Great Firewall -- a lifeline despite Beijing's restrictions.
In January, when Beijing loosened its strict "zero covid" policy that had sealed China off from the rest of the world, ferries between Matsu and Fujian -- which have long allowed people from both sides to visit relatives and check on properties and investments -- resumed service.
A couple of weeks ago, Matsu's mayor, Wang Chung Ming, took a ferry to Fuzhou with a proposal: laying an undersea internet cable between Matsu and Fujian.
The mayor -- a fixture of Matsu's Kuomintang establishment, which has historically maintained closer ties to China than the DPP -- told officials in Fuzhou and the vice chairman of China Mobile Communications Group that he hoped Matsu could be like Kinmen, another Taiwanese island chain a few miles off the coast of China which shares an internet cable connected to southern Fujian.
Though he has laid the groundwork for a deal, the cable outage is a "national security" problem that can't be solved at the local level, he said.
Wang now needs Taipei's approval. "Fuzhou has basically said yes. The rest is up to our side," he said.
The problem posed by the frequent cable breakages -- and their costly repairs -- is one thing officials from Taiwan's two rival political parties can agree on. Kuomintang and DPP leaders have expressed concerns about Taiwan's preparedness for future breaks.
"Taiwan needs to be better prepared in case of any type of emergency, regardless of whether it's a natural disaster or a military threat," said Lii, the head of the local DPP chapter, who called on the international community to help strengthen Taiwan's communication capabilities.
Military analysts and officials said the frequent breaks highlight the vulnerability of Taiwan's internet infrastructure.
"Cable sabotage could become our era's blockade -- and unlike past generations' blockades, it can be conducted on the sly," warned Elizabeth Braw, a fellow at the American Enterprise Institute, in an analysis for Foreign Policy.
Taipei is reportedly in talks with domestic and international investors to establish its own low-Earth-orbit satellite internet service, similar to Elon Musk's Starlink, which has provided internet to Ukraine with some assistance from the United States government.
"When wars occur, this technology has its purpose," said Matsu mayor Wang.
Taiwan's Ministry of Digital Affairs declined to comment on the status of proposals for its own satellite internet network.
In the meantime, a bulked-up version of the microwave radio signal could suffice, Wang said. Taiwan's National Communications Commission said the system is still under construction, and that it would more than double its bandwidth by the end of the year.
Anita Tsai, who runs a restaurant in Dongyin, Matsu's northernmost island, shared the same frustrations over the frequent internet disruptions. "At its worst, it took me five minutes to watch a ten-second video," said Tsai.
Tsai isn't worried about whether the internet comes from a cable, a satellite, a radio wave, or from China -- she just wants her children to be able to attend their online classes.
"Matsu people have always been practical," said the Beigan hotel owner, Wang Yuan-song. "They can't take on matters of ideology, because ideology is not something you can eat."
