Ukraine War Stokes Concerns in Taiwan Over Its Fragile Internet Links (wsj.com) 48

The war in Ukraine is reviving concerns in Taiwan and some Asia-Pacific nations about the fragility of their internet connections because they rely on undersea cables that could be severed in a Chinese attack. From a report: Ukrainians have used the internet to rally resistance to Russia's invasion, counter Moscow's propaganda and win international support, including through President Volodymyr Zelensky's appeals for weapons. Ukraine has extensive internet connections across its land borders and most of the country has remained online despite Russian attacks on internet infrastructure.

In contrast, Taiwan, a self-ruled island that Beijing claims, receives and sends about 95% of its data-and-voice traffic via cables that lie on the seabed. Currently officials say about 14 cables -- bundles of fiber-optic lines about the thickness of a garden hose -- are in operation, and they reach land at four locations on Taiwan's coast. If the cables were to be cut at sea by submarines or divers, or if military strikes were to destroy the lightly protected landing stations, most of the island would be thrown offline. "We're very vulnerable," said Kenny Huang, chief executive of Taiwan Network Information Center, a government-affiliated cybersecurity and internet-domain-registration organization.

  • Ship a bunch of starling terminals there asap.

    • Define "a bunch."

      Enough for military coordination with allies such as the US? OK. Enough to suddenly replace all the load on the cut fiber for civilian such as all the streaming video? Impossible.

  • If some attacker blocks the port and no fuel/food/things can be delivered, then you're basically fsck'ed as well? Sounds to me like the nature of being an island...you're dependend on supply lines for everything you can't or won't produce on your own soil.
  • In a case of attack, if the enemy knows where the country cables are (sometimes this information is wide available), it takes a bunch of well-aimed missiles to cut all connections, except for satellite links.

      "except for satellite links"

      And shortwave radio. Message in a bottle is too slow and unpredictable. Smoke signals. Again, not too practical except under ideal conditions. Coded sonic messages could be broadcast through the ocean. C'mon people, get creative!

    • Well there is anti satellite missiles. I am sure they have Satellite internet connections but not the same sort of bandwidth as cables.

      If we learned anything from Ukraine it is better to be prepared than put in arms after the fact. If Nato had sold Ukraine 25,000 anit armor rockets, anti air systems, anti missile systems prior to the attack then Russia would not have attacked. (Pretty provocative to Russia however in terms of NATO and Russia does not trust Nato or the US with good reason.) The US cannot b
  • they could also receive satellite there assuming the Chinese don't block it.

  • Soon Elon will send 2 rockets with Starlink satellites up per week instead of just 1.

  • Add more undersea cables?

    Nevermind the fact that Taiwan also has satellite links and in the event of a hot war with China would also gain access to US military comms as well, even if they lose general internet. Would suck for the major populace but I doubt Taiwans military or strategic command would be in the dark.

    Also China in this scenario would need to cut pretty much a majority or all the cables, which are also interlinks with other nations in the region so China would be disrupting internet traffic for them as well.

    Looking at a cable map also most of them are on the opposite end of Taiwan in relation to China and in the event of war they would have a short time to get it all done before a few US carrier strike groups are rolled into the area, meaning they could likely provide a fair amount of cover for a repair vessel to start repairing them.

    • I'm not sure what you mean by "opposite end of the island to China", it looks to me like the longs sides of Taiwan is roughly paralell to the Chinese mainland coast.

      When I look at the map I see the largest landing point being Tanshui which appears to be on the China-facing coast, though there also seems to be a landing in TouCheng which is facing away from mainland china.

      Also aside from physical attacks there is also the possibility of economic/business attacks. It seems many of the cable systems serving Ta

      • I meant that that to control those cables China will have to expand naval control out past the Straight of Taiwan and really work more on an encirclement of the island, which leaves them in a much more vulnerable and spread out position if they deem controlling those cables a strategic objective for any length of time. If it's just Taiwan it's probably easy, but in an invasion of Taiwan it's pretty much assured the US Navy and military is involved directly.

        choose between serving Taiwan and Serving mainland China which will they pick?

        If it's a Chinese operator it's obviously China,

      Would suck for the major populace but...

      I think this is a bigger problem than you make it out to be, and one with military and diplomatic consequences. Having stable widely-available internet means that news and reports can move freely and be distributed widely. This can strengthen the resolve of defenders (my comrades are winning / the world's with us / look at what those monsters did / ...) and pushes the world to put political pressure on the aggressor, as we're seeing happen in Ukraine.

      • I agree there ought to be a plan to restrict bandwidth so messages can be sent even if the internet is mostly down. SMS (excluding MMS) for example. The number of those that can get through with less bandwidth than a single video stream is staggering. This goes for natural disaster areas etc too. Enforce a throughput of no more than 1 per phone per second or something to preclude building higher-level protocol on top.

      I would be very surprised if all of those cables don't have some sort of limpet attached offshore that could be triggered to cut them at a moment's notice. The Chinese are not stupid.

  • Period. Next problem?

  • If I were a Taiwan security expert I would think installing backup solutions, like covert cables, or having a secret agreement with an allied country to use space based solutions to be deployed in case of emergency.

    • by gtall ( 79522 )

      Covert cables probably won't work. By the time China invades, they'll have inserted a lot spooks into China and will know where everyone's grandmother lives. Just look at what they do to their own people since the CCP has no respect for them.

  • Wideband LEO satellite Internet links!

You know you've landed gear-up when it takes full power to taxi.
