Thousands of HSBC customers in Britain were unable to access online banking services on Friday due to an outage affecting the bank's website and app. The issue left many customers unable to access their accounts, causing significant inconvenience as some were unable to pay bills. The outage was part of a broader issue affecting several major banks, including Nationwide, Barclays, and Virgin Money. These banks also experienced glitches that prevented customers from making payments and receiving pension payments, leading to widespread frustration. Millions of customers across five banks were affected, particularly on pay day.
