Dirty fibre connections are the number one cause of fibre network failures.
Broadband provider Brsk's full fibre broadband service is now live in the first areas of Accrington.
Giorgio Iovino, Brsk founder and CEO, said: “As our network continues to expand it is fantastic that we have our second region in Lancashire live.
"For the communities of Accrington, this marks a turning point in the way they experience the Internet. Communities now have access to a reliable and high speed connection.
"Communities who are better connected can work more flexibly, access better quality entertainment and make greater use of all that the Internet has to offer.”
