Bank customers across the UK were unable to log in to their accounts this morning because of a major technical fault at internet service provider BT.
The problem, which BT says was resolved by around midday, affected "around 10% of customers' internet usage" a spokeswoman told the BBC.
Some online customers of Barclays, HSBC, Lloyds, Nationwide, Natwest, RBS and Santander were left unable to access their accounts for several hours.
The outage was caused by a power cut at a data centre used by The London Internet Exchange. It comes the day after MPs hit out at BT's Openreach internet infrastructure business for its alleged failure to adequately invest in fast fibre.
