Santander’s UK customers were unable to use online banking and more than 2,000 ATMs yesterday when a power failure occurred at one of the bank's processing sites.
According to the bank, the power failure happened at 11am during internal testing, and the problem was not resolved until 5.30pm. Santander refused to provide any further details.
Customers were still able to pay for products at tills, and obtain a limited amount of cash-back.
Former Abbey and Bradford & Bingley customers were affected by the outage. However, Alliance & Leicester customers were unaffected, and reports suggest that this indicates an issue with the Partenon banking platform.
After acquiring the banks, Santander has moved the IT systems onto a shared Partenon banking platform. This move is not scheduled for A&L’s branches and customers until the fourth quarter of 2010.
Alliance & Leicester customers were not affected by the outage, and reports suggest that this indicates an issue with the share.
Santander acquired Abbey in 2004, and Bradford & Bingley and A&L in 2008.
In November, business continuity questions were raised when a power failure to a datacentre stopped all Halifax and Bank of Scotland branches from being able to provide cash machine, over-the-counter and online services for over six hours.
