In Aberhosan, a small village in Powys, Wales, broadband disappeared every morning around 7 a.m. The outages lasted 18 months. The culprit wasn’t a faulty cable or a storm, but an old second-hand television, switched on at the same time each day by a resident.
Eighteen months of outages, an entire village, and a second-hand set.
- A Welsh village experienced daily, regular internet outages at 7 a.m. for 18 months.
- An old second-hand television switched on at the same time every day emitted an electrical interference that scrambled the entire network.
- Ordinary domestic electrical faults can affect an entire internet network when the equipment isn’t properly protected.
Cables Replaced for Nothing
The outage had a strange signature. Each morning around 7 a.m., broadband disappeared across the entire village, not just a few homes. The logic suggested we suspect the network, so cables were replaced. With no effect: the outage returned the next day at the same hour.
This regularity could have served as a clue. Cable wear, rain, or a traffic spike rarely follows such a strict schedule, whereas a daily action repeated at the same minute does.
The engineers at Openreach, the company responsible for maintaining the UK network, eventually changed their approach. They toured the village with a spectrum analyzer, a device that detects electrical interference on lines. At 7 a.m., “like clockwork,” the phenomenon reappeared before their eyes, and the trail led to a house.
SHINE, a parasite that interferes with the line
In that house, a resident turned on every morning his old second-hand television. The set emitted an electrical interference that technicians refer to by the acronym SHINE, for “single high-level impulse noise,” namely a single high-intensity electrical impulse noise. This parasite scrambled the village line. The question remains: why could a single television disrupt everything? An old device is likely less well protected than a modern model, but the briefing does not specify.
The owner said he was mortified.
He promised never to use the set again. Since then, the outage has not returned. The BBC announced the case on September 22, 2020, and the Aberhosan incident became the quintessential example of a fault looked for miles away, while it was only a few meters from a socket.
Your router isn’t always the culprit
This story echoes others. Mysterious signals picked up by a radio telescope were eventually traced to the microwave oven in a kitchen. In both cases, the cause was banal and familiar, and thus dismissed too quickly.
In your home, a regular drop in the connection deserves the same reflex as in Aberhosan. Note the exact time of outages for several days, then look for what turns on at that moment: television, an old device, second-hand equipment plugged in at home or at a neighbor’s. You won’t have a spectrum analyzer, but you can proceed by elimination, unplugging suspect devices one by one and watching whether the line holds.
Of course, the router remains a legitimate suspect, and an operator can check the line before any other test. But faulty hardware isn’t always what you rent: it can also be the item you bought second-hand, which has run for years without anyone worrying.
One detail still missing from the story: the exact discovery date isn’t known; only the dated announcement of September 22, 2020 exists.
