EXCLUSIVE: Tony O’Sullivan warned our web would develop into painfully sluggish and unresponsive “inside hours”.

Britain’s heavy reliance on a fragile internet of subsea web cables leaves it uncovered to disruption that would sluggish the nation to a crawl inside hours, an business skilled has warned. The stark evaluation comes as Defence Secretary John Healey disclosed that British and allied forces tracked Russian submarines working round crucial undersea infrastructure earlier this month.
Whereas no harm was reported, the operation — attributed to exercise linked to Vladimir Putin — has intensified concern concerning the vulnerability of the UK’s digital spine. Tony O’Sullivan of RETN stated the thought of a seamless and resilient “international community” masks a extra fragile actuality beneath the floor.

Mr O’Sullivan stated: “The business likes to name them ‘international networks’, however in actuality, an enormous share of site visitors funnels via a handful of slim corridors.” These corridors, together with elements of the English Channel and the North Sea close to the Strait of Dover, have develop into focal factors for international information flows as a result of geography and price.
However that comfort comes with threat. Mr O’Sullivan stated: “Beneficial doesn’t imply fully secure. Many of those identical corridors are additionally in style delivery lanes and fishing spots, making unintentional harm a giant threat.” He confused that such incidents — usually attributable to anchors or fishing tools — are already the first supply of cable outages worldwide.
Mr O’Sullivan stated: “These are the actual causes of most outages, somewhat than deliberate sabotage. As a lot capability runs alongside these routes, in the event that they do get affected, it doesn’t affect the sting of the web spine, however a serious conduit.” Regardless of heightened fears about hostile state exercise, Mr O’Sullivan stated the fast hazard shouldn’t be a sudden nationwide blackout.
Mr O’Sullivan stated: “It’s a false impression that cables get minimize, and the web instantly goes darkish. It depends on a mesh of networks that’s extremely unlikely to fail.” As a substitute, disruption would construct rapidly and visibly. He stated: “Site visitors would merely discover one other path to take. Nevertheless, efficiency may degrade rapidly.”
He stated: “Inside hours, various pathways may develop into unstable beneath the load, and congestion would pile as much as the purpose the place the web… turns into painfully sluggish and unresponsive.” For households, that might imply on a regular basis digital companies faltering.
Mr O’Sullivan stated: “Funds not going via, feeds failing to replace, and messages taking longer to ship,” including that “crucial companies, comparable to healthcare techniques or banking apps, may additionally come beneath pressure.”
The results for companies may very well be extra extreme, notably for these reliant on real-time connectivity or cloud-based techniques. Mr O’Sullivan stated: “The affect on particular person companies would rely upon how effectively they’ve designed and invested of their networks and companies,” warning that companies which fail to organize “can pay the worth when disruption hits.”
The size of the infrastructure problem is huge. The UK is determined by dozens of subsea cable techniques, together with main transatlantic hyperlinks stretching 1000’s of kilometres. Mr O’Sullivan stated: “It’s unlikely they may patrol the community in its entirety. The UK depends on 1000’s of miles of submarine cables… and that’s one in all roughly sixty routes that the UK is determined by.
As a substitute, he argued that resilience should come from higher design and funding. Mr O’Sullivan stated: “A extra real looking repair… is constructing and, extra importantly, utilising routes that don’t all sit in the identical place. There was funding, however the uncomfortable reality is the business hasn’t moved quick sufficient.”
That lag is now colliding with rising geopolitical threat — and growing prices. Mr O’Sullivan stated: “The fact is, resilience isn’t free. The price of extra advanced routing, larger insurance coverage, and elevated capability provides up.” Whereas firms have to this point absorbed a number of the monetary strain, he warned: “It’s solely delaying the inevitable.”
The result’s a rising mismatch between the UK’s deep dependence on uninterrupted connectivity and the resilience of the infrastructure supporting it.
Britain might not go offline fully. Nevertheless, as Mr O’Sullivan’s warning makes clear, even restricted disruption may very well be sufficient to carry giant elements of its digital economic system grinding in direction of a standstill.
