LONDON (Reuters) - HSBC suffered its second online banking outage in four days in Britain on Monday, as customers complained on social media that they could not log in.
HSBC said it had resolved the problem, which lasted around 30 minutes and was due to a temporary technical issue.
HSBC customers had also said on Friday they were unable to access online accounts, when many were expecting pay cheques.
The bank said that disruption was caused by a scheduled upgrade which failed to complete properly.
Disruption to online and mobile services has become more of a problem for banks in recent years, as lenders cut branch networks and steer customers towards those digital platforms.
