He said the investigators set out to determine whether electrical interference was to blame.
"We walked up and down the village in the torrential rain at 6 a.m. to see if we could find an electrical noise to support our theory. And at 7 a.m., like clockwork, it happened. Our device picked up a large burst of electrical interference," engineer Michael Jones said.
Jones said the team traced the interference to a home, where they discovered its surprising origin: an elderly resident's old TV set.
The broadband outages coincided with the resident's daily routine of switching on the TV set at 7 a.m.
"As you can imagine, when we pointed this out to the resident, they were mortified that their old secondhand TV was the cause of an entire village's broadband problems, and they immediately agreed to switch it off and not use it again," Jones said.
