Engineers from a local internet service provider (ISP) took more than 18 months to discover what has been disrupting the Internet and telephone services at a Welsh village, every day without fail at 7 in the morning.
In the small village of Aberhosan, in the Welsh area of Powys, subscribers of more than 400 residents consistently lost their broadband internet and telephone service. After a thorough inspection of the locale, the ISP finally discovered the source of all the commotion.
A Surprising Source of Electrical Interference
According to Openreach, the Internet service provider that provides Internet broadband and telephone services in Britain, they sent engineers to respond after all of the village's residents complained about losing their Internet services. Investigators got to work on finding a possible source of electrical interference.

"We walked up and down the village in the torrential rain at 6 am to see if we could find an electrical noise to support our theory," said Openreach engineer Michael Jones. "And at 7 am, like clockwork, it happened."
The team then traced the electrical interference to a surprising source - a 16-inch Bush television set owned by retired couple Alun and Elain Rees. Furthermore, the village-wide service interruption perfectly coincides with the Rees' daily routine of turning the television on in the morning.
A retired receptionist, 63-year-old Elaine, shared that she would turn her TV on at seven in the morning to watch the show "Good Morning Britain," expressing love for its host Piers Morgan.
When the engineers from Openreach explained the situation to the elderly Aberhosan resident, they "immediately agreed to switch it off and not use it again," according to Jones.

A Village-Wide SHINE
The Openreach engineers investigated the source of the interference using a spectrum analyzer - a device that measures the magnitude of a target signal, revealing loss or attenuation due to noise.
"Not being able to solve the fault for our customers left us feeling frustrated and downbeat, but we were determined to get to the bottom," Jones shared in an interview with online Internet review and news portal ISPreview.
After their initial searches turned out negatively, the tech team lastly wanted to check if the fault was caused by SHINE - Single High-Level Impulse Noise. It is a phenomenon where high levels of electrical interference are caused by equipment, like a home appliance, that interrupts broadband signals within range.

According to American Internet service provider Sonic, either radio frequency (RF) or electromagnetic interference (EMI) can disrupt DSL - which provides telephone and internet services. Most likely, the EMI from old TVs, made from Cathode Ray Tube (CRT) technology, has caused the clockwork interruption.
Also, according to Openreach, they plan to migrate the Aberhosan subscribers to a fiber-based network. Using fiber optic cables instead of traditional wires will transmit light pulses instead of electrical signals, making them impervious to RF or EMI interference.
