Not even the most experienced engineer seemed to be able to solve the problem, which after all had a very ‘analog’ solution, which was only discovered 18 months later.
Every day at 7am – one would say, ironically, from British punctuality – the town of Aberhosan in Powys, Wales, had no internet.
The situation remained unexplained for 18 months, there was an exchange of equipment, studies by specialized equipment, but only now has the mystery been solved.
For a year and a half, despite repeated visits by engineers to detect and correct the fault, the mysterious problem remained. The tests that were carried out showed that the network was working well, but the network cables were still replaced. And yet the problem has not been solved.
After all possibilities were exhausted, which included bringing a special team of engineers to the site, a final test was carried out to assess the possibility that the failure could be caused by a phenomenon known as Shine [Single High-level Impulse Noise], a kind of electrical noise from a device that can interfere with the broadband connection.
With the help of a meter – called the Spectrum Analyzer – they were able to detect this Shine and discover the origin of the signal sent by the network to the entire town below, which originated from a house.
Then I found out what happened every day at 7 am in that house in the village.
“It was exactly at this moment, that a couple living in the town turned on their old television, which when starting up the broadband of the entire town,” explained the operator’s engineer, quoted by the BBC television network.
Truly embarrassed, the couple, who asked not to be identified, vowed never to turn on the old television. Since then, no other network failure has been recorded.
