Businesses and homes across the UK have lost broadband connection after BT confirmed a power issue at a major exchange in Birmingham has caused serious problems.
Customers all over the UK have been affected, from London and Swansea to Belfast and Edinburgh.
Further to that many disgruntled customers have turned to Twitter to vent their frustration at BT for not answering their helpline.
"We're aware that a number of you are unable to get online," BT said on Twitter.
"This is due to a power issue. We're sorry about this & will keep you updated."
