Subsea Cables & Internet Infrastructure

CNN reports that two American government officials say the most likely explanation for the outages is simple irresponsible behavior by a Chinese cargo ship dragging its anchor. This contrasts sharply with German and Finnish officials who have insisted on sabotage. My own take is that the Americans are right. Nothing about the sabotage hypothesis is convincing.  There is no recorded incident of state sabotage of subsea cables since WWII's end.  Fishing boats and cargo ships dragging their anchors are responsible for approximately 70% of outages with the balance due to events such as debris slides in subsea canyon, loss of power, subsea earthquakes going mudslides, etc. Historical data provides no examples of state targeting of subsea fibre optic infrastructure. Most subsea cables are buried 1 to 2 meters deep to prevent damage. So locating them is difficult even for cable repair ships. Repair of the subsea cable SWM5 was delayed several weeks because the ship could not locate the ca

"Two subsea cables located in the Baltic Sea have recently reported faults. BCS East-West cable reportedly experienced a fault at 08:00 on Sunday 17th November and the C-Lion cable reportedly experienced a fault at 02:00 on Monday 18th November (times UTC).  There has been speculation and opinion shared on social media and from news outlets as to the causes of these two subsea cable faults. Many commentators have pointed towards deliberate action. However, at this stage there is no evidence to make any conclusive statement. Particularly since the Nord Stream Pipeline was damaged in 2022, the security of critical undersea infrastructure has been a central topic of discussion, and action, for both industry and government. For these and future incidents it is prudent to consider the following: -       The primary causes of cable damage in Northern European waters are commercial fishing or ship anchors, with a smaller proportion of faults caused by natural hazards (seafl
