Beaver was accused after a town in British Columbia, Canada, lost internet service for about 12 hours.
Provider Telus said some of the underground cables servicing Tumbler Ridge were found in Beaver’s home.
It said that about 900 Internet users and 60 TV customers were affected.
Telus spokeswoman Liz Sauvé described it as “a very rare and unique Canadian event.”
The service stopped around 04:00 local time on Saturday.
According to Tellus, when the crew went to a nearby dam, the beaver was found to have “bitten the fiber optic cable in multiple places, causing major damage.”
The cable was buried about 1 meter (3 feet) underground and protected by a 12 cm (4.5 inch) thick conduit.
Telus said it had fully restored service to Tumbler Ridge, a population of 2,000, by 15:30 on Sunday.
Beavers are Canadian animals, but they have a mixed reputation. Rodents are loved as the ultimate environmental engineer whose dam construction skills bring a variety of ecological benefits.
However, their incredibly strong teeth can cause enormous damage, and farmers in particular are worried about the havoc they can cause to their crops and trees.
Just two weeks ago, the mayor of the Quebec town of Grenville-sur-La Rouge accused them of a massive flood that damaged property and infrastructure.
Approximately 800 beavers have built about 200 dams around the town, and Mayor Tom Arnold said he needed more flexibility to manage rodents.
“That’s a problem we need to get rid of. Beavers have to be eradicated,” he said, quoted by CBC News.
Beaver is slowly being reintroduced into parts of the UK Hope they help restore wetland habitat. They were endangered in the 16th century due to their fur, flesh and scented glands.
