So last night NatWest customers began seeing this message when they logged into their online banking.
However, Twitter users such as Nick Bain pointed out that that is when tickets for next year's Glastonbury festival go on sale.
And some people started to get worried they might miss out on the chance to secure tickets for the 2015 festival at Worthy Farm.
But this morning NatWest began reassuring its customers that debit card payments would be working as normal on Sunday.
Halifax also reassured customers it would not be doing anything to cause a disruption.
NatWest has confirmed to BuzzFeed News that debit card payments will not be affected at the weekend, just bank transfers and online and mobile payments.
