In a statement apologising to customers, a spokesman said: “We are now experiencing issues with our Online and Mobile banking”.
The bank’s personal banking portal is experiencing service issues, following problems yesterday, and users are unable to log in.
HSBC announced the outage on Twitter shortly after it discovered the problems, but this did not seem to appease numerous company’s customers.
HSBC said it was not a distributed denial of service (DDOS) attack and was not caused by anything external.
It also advised that its mobile app is still working.
Business customers were experiencing “significantly reduced capacity”, with all services running much more slowly than normal, HSBC said.
The exact cause of the problems remains unclear as HSBC says it is working to restore the service. “Regular updates will be provided”, he said.
The systems went down at 8am yesterday morning and, as ever, customers took to Twitter to vent their anger, with one customer saying, “Nightmare”.
“It’s incredibly frustrating and we’re not getting a lot of information from HSBC other than their brief messages on Twitter”.
Telephone banking is still available, but HSBC warned that call volumes would be high. It was 10 hours ago HSBC tweeted, “We apologise for today’s service disruption and thank you for your patience”. Business customers should call 03457 60 60 60.
Any customers with urgent queries should call Business Telephone Banking on 03457 60 60 60 or Personal Telephone Banking on 03457 404 404.
Otherwise customers should go to their local branch, HSBC said. In the summer around 275,000 HSBC bank payments were held up by a computer glitch.
