Nigerian officials are calling this "cut cables" and a few weeks ago this happened:

“There have been significant fibre cuts [by road contractors] across the country, and this has impacted connectivity ”

At this spot chem tanker KPS Arya Sultan moved slowly in a cable area 24-03-14 03:25-06:44Z. Further idled across cables 24h a day before. The areas are very deep though, 300-700m and 2.5-3.5km respectively.

This is not an accusation, merely a note. Did not find any other ships

EDIT 20.03.2024-tegu siis 13 riigi internetiühendusi mõjutava katkestusega

Thirteen countries across Africa experienced Internet outages on Thursday due to damage to submarine fiber optic cables. Some countries, including Ghana and Nigeria, are still suffering from nationwide outages.

Multiple network providers reported Internet outages yesterday, and Cloudflare's Radar tool, which monitors Internet usage patterns, detailed how the outage seemingly moved from the northern part of West Africa to South Africa. All 13 countries (Benin, Burkina Faso, Cameroon, Côte d'Ivoire, Ghana, Guinea, Liberia, Namibia, Niger, Nigeria, South Africa, The Gambia, and Togo) reportedly suffered nationwide outages, with most seeing multiple networks hit.

Some countries' Internet disruptions were short-lived, such as in Gambia and Guinea, as they lasted for 30 minutes, per Cloudflare. Other outages, like in South Africa (five hours) were longer, and some remain ongoing. As of this writing, Cloudflare reports that six countries, including Benin, Burkina Faso, Cameroon, and Côte d'Ivoire, are still suffering outages.

Numerous sources, including local network providers like Vodacom, MTN, and the Nigerian Communications Commission, reported that damage to multiple undersea cables is to blame. A Thursday press release from Reuben Muoka, director of public affairs at NCC, said: "The cuts occurred somewhere in Cote d’Ivoire and Senegal, with an attendant disruption in Portugal."

In an Azure status report, Microsoft said it "determined" that "multiple cables" on the West African coast, including Africa Coast to Europe, MainOne, SAT3, and West Africa Cable System, were disrupted. You can see a map of the cables that were damaged here. The source of the cable damage is undetermined.

"In addition to these cable impacts, the ongoing cable cuts in the Red Sea—EIG, Seacom, AAE-1 — are also impacting overall capacity on the East Coast of Africa. These incidents together had reduced the total network capacity for most of Africa's regions," Microsoft said.

Kanadas lõigati läbi Ontario provintsis Niagara piirkonnas olnud fiiberoptilised kaablid

Cogeco internet is down for an entire Niagara / Hamilton region because someone tried to steel copper wiring and severed the fibre optic cable that serviced the entire region.

Ontario not in a great way at the moment

https://x.com/quartermass/status/1796874099878199426

We have teams on site to repair the cut fibre due to vandalism, affecting our services in Hamilton, Niagara Region, and the surrounding areas. This involves splicing approximately 182 fibre optic cables in the 3 wires that have been cut.

Unfortunately, we don't have an exact time for when this will be resolved, but rest assured, our team is working hard to get everything back up and running as soon as possible.

Pikem lugu Norra Lofootidel toimunud merealuste sidekaablite lõhkumisest 2021 aastal ja ka 2022 aastal Teravmägedel.

Born in Norway and educated in China, Zhang is brusquely matter-of-fact in a way that feels true to both cultures—in conversation, he doesn’t fill silences. Much of his work involves a set of five powerful microphones strung along a 31-mile cable on the floor of the Norwegian Sea called the Lofoten-Vesterålen Ocean Observatory. Known as LoVe to the researchers who run and maintain it, it’s mostly a scientific tool, but it’s also used by Norway’s military, which removes sensitive information before releasing the rest to the public. The government is vague about how it uses the data but acknowledges it could serve to identify specific ships in the area, whether those of Norway’s own military, its NATO allies or its adversaries. That also makes it an unorthodox part of the surveillance apparatus monitoring the increasingly provocative activities of Norway’s neighbor to the east, Russia.

In April 2021, Zhang was just back from Easter break when he noticed the LoVe observatory had gone quiet. It wasn’t unusual for the cable to have problems—the isolated northern region where it leaves the shore often has power outages. But when Zhang rebooted the computers remotely, there still wasn’t any data coming in. When he contacted technicians from the IT company that had installed the equipment, they didn’t have any luck either.

Finally, five months after the outage, Equinor ASA, Norway’s state-owned petroleum company and a partner on the observatory, informed the institute it would sponsor a mission to examine the cable. The company offered Zhang and his colleagues the use of the Havila Subsea, a 321-foot-long support vessel Equinor had chartered for an unrelated job.

On Sept. 10, the researchers gathered around a computer in Bergen, watching a live video feed from one of the drones—a boxy 8,000-pound robot measuring 6 feet by 6 feet by 10 feet with a pair of hermit-crab-like arms. As it descended, the glare of its lights caught krill jackknifing past its camera lens. The observatory’s yellow data cable soon emerged out of the blue-green haze, then the relay unit: a van-size metal cage, also yellow, protecting the equipment inside. At the approach of the submersible, fish that were sheltering inside the cage drifted lazily out.

Then the drone circled the cage, and Zhang had trouble believing what he saw. The output side should have been identical to the unit’s input side—the same machinery, the same cable extending north toward the next relay unit. But there was none of that. The equipment on that side had been ripped out, and the 12-ton section of cable attached to it was missing.

“It had been there for three years, and suddenly it’s gone,” he recalls. The cable hadn’t malfunctioned; it had disappeared. Someone, or something, had taken it.

The following day, the ship’s crew deployed the drone again to recover the cable. In a feat of robotic dexterity, the operator used the remote-controlled arms to knot a large chain around the cable, attaching it to a powerful pulley that slowly hoisted it and winched it into a large drum on the G.O. Sars.

Police officers joined Zhang a week after the recovery at a storage facility the institute uses in Bergen. It was the first time he was taking a close look at the end where the cable had been separated from the relay unit, and he noticed something significant. If the cable had been torn apart or cut by a trawl door, the break would have been jagged and uneven. But instead it had been sliced through cleanly, with some kind of power saw. That was hard to square with the idea of an accident.

The maps showed about a dozen ships. Most of them had spent that April 3 tracing long arcs through a fishing ground a little to the southwest of the two relay units bracketing the missing segment. But one ship, a 197-foot-long, Russian-flagged trawler called the Saami, had behaved differently. Traveling at about 10 knots, it had passed back and forth over the LoVe cable at least four times. “I saw this boat, only this one boat, cross the cable at this time,” Zhang says. “I locked my suspicion on this one boat.” Once he’d narrowed his parameters to the span of time when the cable disappeared, the paths of the other ships dropped away on his computer screen, leaving just the tight scribble traced by the Saami. At the precise moment the cable went dead, the ship was right above it.

2022 aastal Teravmägede sidekaabli lõhkumine

And there his investigation, like Zhang’s, ran into a wall. Soon thereafter, however, he got another, similar case. Around 5 a.m. on Friday, Jan. 7, 2022, a 900-mile communications cable running from the Norwegian mainland to the far northern island of Svalbard stopped working. It was one of two cables servicing the Svalbard Satellite Station, the world’s largest ground station for collecting data from polar-orbiting satellites, including meteorological and other imagery that has dual civilian and intelligence uses for American and European government agencies. The technicians from Space Norway, the company that operates the cables, determined later that water had somehow gotten into one of the cables, causing an electrical short, and the power had gone out.

Journalists with the Norwegian Broadcasting Corp. later determined that a Russian-flagged fishing trawler, the Melkart-5, had crossed the cable’s path 130 times around the time it was damaged. One expert, speaking in a documentary film jointly produced by a group of Nordic public broadcasters, described the ship’s pattern of movement as “completely illogical.”

Kanadas lõhuti tahtlikult merealune fiiberoptiline kaabel

Canada’s undersea fiber optic cable damaged

While it’s not clear who cut through the steel-wrapped cable between Cape Breton Island and Newfoundland's west coast, the investigation has discovered “a telltale sign,” Canadian television channel CBC reported.

"There's almost like a cut, or like an angle grinder cut, through the cable," telecommunications giant Bell's director of networks David Joyce said, adding that “it’s a pretty tough thing to do."

The cable was cut for the second time on Dec. 24, 2024, after being sliced similarly in December 2023.

Telecommunications giant Bell is exploring surveillance options in the Gulf of St. Lawrence after one of its subsea fibre optic cables between Cape Breton Island and Newfoundland's west coast was recently severed for the second time.

David Joice, the company's director of networks, said it's suspected that an anchor or a piece of gear, such as a trawling net, snagged the cable last Dec. 24. He said the cable was then brought to the surface along with the gear, and deliberately cut by someone.

"The telltale sign that we have is that there's almost like a cut, or like an angle grinder cut, through the cable," Joice said in a recent interview with CBC Radio's Information Morning Cape Breton.

"That's a pretty tough thing to do because ... it's just not like a fibre optic cable that you'd see on the poles or going to your home, but it's actually wrapped in steel. So it takes a lot of effort to actually cut."

The 140-kilometre cable, which runs from Dingwall, N.S., to Codroy, N.L., was also sliced in a similar way in December 2023. Who cut the cable and why remains a mystery in both cases.

According to telecommunications company Quintillion, early Saturday morning there were several reports of widespread network outages affecting Northwest Alaskan residents. Upon review by the Quintilion team, it was determined the outage was caused by a subsea fiber cut in the Beaufort Sea.

Quintillion has an approximately 1,180 mile-long subsea fiber cable network that spreads throughout Northern and Western Alaska, and this outage will affect each stop along the route.

Microsoft says Azure customers may face latency issues after multiple undersea cables in the Red Sea were cut.

https://x.com/clashreport/status/1964428419707367700

DUBAI, United Arab Emirates — Undersea cable cuts in the Red Sea disrupted internet access in parts of Asia and the Middle East, experts said Sunday, though it wasn’t immediately clear what caused the incident.

There has been concern about the cables being targeted in a Red Sea campaign by Yemen’s Houthi rebels, which the rebels describe as an effort to pressure Israel to end its war on Hamas in the Gaza Strip. But the Houthis have denied attacking the lines in the past.

Undersea cables are one of the backbones of the internet, along with satellite connections and land-based cables. Typically, internet service providers have multiple access points and reroute traffic if one fails, though it can slow down access for users.

Microsoft announced via a status website that the Mideast “may experience increased latency due to undersea fiber cuts in the Red Sea.” The Redmond, Washington-based firm did not immediately elaborate, though it said that internet traffic not moving through the Middle East “is not impacted.”

NetBlocks, which monitors internet access, said “a series of subsea cable outages in the Red Sea has degraded internet connectivity in multiple countries,” which it said included India and Pakistan. It blamed “failures affecting the SMW4 and IMEWE cable systems near Jeddah, Saudi Arabia.”

The South East Asia–Middle East–Western Europe 4 cable is run by Tata Communications, part of the Indian conglomerate. The India-Middle East-Western Europe cable is run by another consortium overseen by Alcatel-Lucent. Neither firm did not immediately responded to requests for comment.

Pakistan Telecommunications Co. Ltd., a telecommunication giant in that country, noted that the cuts had taken place in a statement on Saturday.

Saudi Arabia did not immediately acknowledge the disruption and authorities there did not respond to a request for comment.

In the United Arab Emirates, home to Dubai and Abu Dhabi, internet users on the country’s state-owned Du and Etisalat networks complained of slower internet speeds. The government did not immediately acknowledge the disruption.
