St George Bank's Web site suffered a "brief "outage this morning, leaving thousands of customers unable to connect to the bank's homepage or its Internet bank.
A spokesperson from St George said the bank is investigating the cause of the "very minor outage" which occurred for 20 minutes from 9:30 this morning.
"It was what we called a degradation of service, where some customers might have been able to get on, while some customers might have had some difficulty in the brief timeframe. It would not have affected all customers," the spokesperson said.
While admitting the cause of the outage is unknown, the spokesperson said the bank's server was rebooted once alerted to the problem.
