The internet's backbone is vulnerable to forces far beyond control
Beneath the Red Sea, four submarine cables have been severed, silencing a quarter of all internet traffic between Asia and Europe and touching roughly 17 percent of global connectivity. The damage, confirmed by HGC Global Communications, lays bare how profoundly the modern world depends on infrastructure it rarely contemplates — thin lines of fiber resting on the ocean floor, carrying the weight of commerce, communication, and finance. Responsibility remains bitterly disputed, with Houthi rebels blaming American and British naval operations while Yemen's government accuses the group of systematic attacks on the arteries of global civilization. The incident is less a technical failure than a reminder that geopolitical conflict has always found its way to the most vital and vulnerable passages of human connection.
- Four cables failing simultaneously has pushed internet service providers into emergency rerouting, exposing just how little redundancy exists in one of the world's most critical maritime corridors.
- With 80 percent of Asia's westbound internet traffic dependent on these Red Sea pathways, the math of disruption is unforgiving — and no quick repair is possible for infrastructure lying at the bottom of the sea.
- The blame war is as tangled as the cables themselves: Houthi authorities point to US and UK naval operations, while Yemen's internationally recognized government accuses the rebels of deliberately targeting global communications infrastructure.
- Telecommunications companies are scrambling to redirect traffic and shield clients from cascading damage, but the workarounds are stopgaps, not solutions.
- The incident has reignited urgent questions about how critical undersea infrastructure can be protected in a region where geopolitical tensions make even the facts of destruction a matter of dispute.
Four submarine cables beneath the Red Sea have been severed, taking with them roughly a quarter of all internet traffic between Asia and Europe and disrupting an estimated 17 percent of worldwide connectivity. HGC Global Communications, headquartered in Hong Kong, confirmed the damage and offered a stark illustration of the stakes: about 15 percent of Asia's outbound internet traffic travels westward, and some 80 percent of that flow depends on these very cables. With four of them dark at once, the company has been forced into emergency rerouting while working directly with affected clients — though no swift remedy exists for infrastructure resting on the ocean floor.
Who bears responsibility remains fiercely contested. Yemen's government-affiliated telecommunications companies had warned in early February that Houthi rebels posed a threat to the cables, and the government has since accused the Iranian-backed group of systematically targeting global communications infrastructure. The Houthis, however, deny any involvement, instead blaming US and British naval operations for provoking the damage — a claim their Ministry of Transport formalized in an official statement, while pledging commitment to protecting the cables under international law.
The Red Sea incident is not without historical precedent — Taiwan's 2006 earthquake caused comparable submarine cable failures — but this rupture carries a different gravity. These cables are not peripheral; they are essential conduits of global commerce and finance, and their failure produces no graceful degradation, only disruption and delay. As telecommunications firms work to restore normalcy, a deeper question surfaces: in a region where geopolitical conflict is constant and accountability is disputed, how can the world's most critical and most invisible infrastructure ever truly be made safe?
Four submarine cables running beneath the Red Sea have been severed, and with them went a quarter of all internet traffic flowing between Asia and Europe. The damage, confirmed Monday by HGC Global Communications, has disrupted roughly 17 percent of the world's total internet traffic—a staggering proportion of global connectivity routed through cables most people will never see or think about.
The four cables belong to major telecommunications networks, and their simultaneous failure has forced internet service providers into emergency mode. HGC, headquartered in Hong Kong, explained the scale of the problem with a simple statistic: about 15 percent of Asia's outbound internet traffic heads westward, and roughly 80 percent of that westbound flow depends on these Red Sea cables. When four of them go dark at once, the math becomes brutal. The company has begun rerouting traffic to other pathways and is working directly with affected clients to minimize the cascading damage, but there is no quick fix for infrastructure that lies at the bottom of the sea.
Who cut the cables remains contested. Yemen's government-affiliated telecommunications companies warned in early February that the infrastructure faced attack risk from Houthi rebels, the Iranian-backed militant group that controls much of northern Yemen. The Houthis, however, have flatly denied involvement. Instead, they have pointed fingers at the United States and Britain, claiming that hostile naval operations by American and British warships caused the damage. On Saturday, Yemen's Houthi-controlled Ministry of Transport issued a statement asserting that British and American naval actions "provoked defects in the submarine cables in the Red Sea." The ministry added that the group remains committed to protecting the cables in accordance with international law and treaties.
Yemen's government, which opposes the Houthis, has responded with its own accusation: the group has been "systematically attacking" global communications infrastructure and the international banking system. The government warned months ago that Houthi actions posed a threat to worldwide connectivity and called the militant group a terrorist organization. An international Gulf forum report published weeks before the cable damage raised the possibility of Houthi involvement in such attacks, lending weight to the government's claims.
This is not the first time undersea cables have failed catastrophically. During Taiwan's 2006 earthquake, submarine cables suffered significant damage, disrupting connectivity across the region. But the Red Sea incident carries different weight because it sits at the intersection of geopolitics and critical infrastructure. The cables that run through those waters are not redundant; they are essential arteries of global commerce, communication, and finance. When they fail, there is no graceful degradation—only rerouting, delay, and the uncomfortable realization that the internet's backbone is vulnerable to forces far beyond the control of the companies that depend on it.
Telecommunications firms are working to restore service and manage the fallout, but the larger question lingers: how many more cables can fail before the system itself becomes fragile? And in a region where geopolitical tensions run high, how can critical infrastructure be protected when the parties involved cannot even agree on who broke it?

La Conversación del Hearth Otra perspectiva de la historia
When you say 17 percent of global internet traffic, does that mean the entire internet slowed down everywhere, or just certain regions?
It's more precise than that. The damage specifically cut Asia-Europe connections, so someone in Tokyo trying to reach a server in London would feel it immediately. But someone in New York accessing a US-based service wouldn't notice. The 17 percent figure tells you how much of the world's total traffic normally flows through those cables—it's a measure of their importance, not a measure of universal slowdown.
Why are there only four cables? Shouldn't there be backups?
There are other cables, which is why the internet didn't collapse entirely. But these four were apparently the most direct and efficient routes for that particular traffic corridor. When you lose the fastest path, you have to take slower detours. It's like losing four lanes on a highway—other roads exist, but they're congested now.
The Houthis deny it, the government blames them. How do we actually know what happened?
We don't, not yet. That's the uncomfortable part. The cables are underwater, damaged, and no one has inspected them closely enough to say definitively whether they were cut by military action, ship anchors, or something else. Both sides have incentive to lie.
Is this a new kind of warfare?
Not new, but it's becoming more visible. Submarine cables have always been vulnerable—they're essentially unguarded infrastructure worth billions. What's changed is that geopolitical actors are now openly willing to target them, or at least willing to be accused of it. The Red Sea is a chokepoint, and chokepoints attract conflict.
Can the cables be repaired quickly?
Not quickly. You need specialized ships, divers, and the ability to work in contested waters. HGC is rerouting traffic to buy time, but actual repair could take weeks or months. In the meantime, internet companies are paying more to use alternative routes, and that cost gets passed along eventually.
What happens if this keeps happening?
Then the internet becomes less reliable, more expensive, and more fragmented. You start seeing regional internets instead of a global one. That's not science fiction—it's what happens when critical infrastructure becomes a target.
