Ulster Bank Pledge After Suffering IT Problems
Ulster Bank has promised to reimburse customers left out of pocket after technical problems hit salary and other payments.
Euro customers expecting transfers and wages paid into their accounts overnight were affected by a delay but the issue has been fixed, it said.
Many people claimed they were unable to access current transactions, wages being paid into accounts and other payments.
It is not known how many customers or payments were affected by the glitch - the latest in a series of embarrassing technical failures.
The bank, which is owned by the Royal Bank of Scotland (RBS), said: "Some files were delayed through our payment system overnight and these payments have now been made.
"We apologise for this delay and if any customers have been left out of pocket, we will put this right."
The bank apologised on Twitter and tried to reassure customers in Northern Ireland and the Republic that the technical issue would only affect payments for a few hours.
RBS itself suffered a major IT fault last week that left customers unable to use debit or credit cards for a three-hour spell on what was expected to be the busiest online shopping day before Christmas.
An estimated 750,000 RBS, NatWest and Ulster Bank customers were affected.
Days later its websites fell victim to a cyber attack which also caused problems.
RBS, which is 80% owned by the UK Government, has been beset by system failures, including a major meltdown last summer.
The bank's new chief executive, Ross McEwan, admitted it had not invested properly for decades.
