The IndependentWhen will it be fixed?
Sadly, there doesn't appear to be any quick fix to the problem.
Writing on X, formerly know as Twitter, Crowdstrike chief executive George Kurtz said: 'The issue has been identified, isolated and a fix has been deployed.'
However, in an interview on NBC's Today Show in the US, Mr Kurtz admitted 'it could be some time for some systems that won't automatically recover.'
Industry expert Adam Leon Smith of BCS, the Chartered Institute for IT, warned that it could even take 'weeks' for all computers and systems to be fully restored.
'The fix will have to be applied to many computers around the world. So if computers are getting blue screens and endless loops, it could be more difficult and take days and weeks,' he said.
What can you do if affected?
If your bank or building society has been affected by the IT outage, here's what you can do:
Contact your bank
If you can, go to your local bank branch - especially if you urgently need to access your money. If you don’t have a local bank branch nearby or transport to get to it, try and call your bank and ask for its guidance on what to do.
That's assuming telephone banking isn't also down. If that's the case, or lines are busy, try contacting your bank on social media to ask what to do. But don’t ever share your account details over social media.
If you have no luck getting in touch with your bank and you’re not able to access your money, start gathering evidence for a complaint. Make a note of who you speak to, the time and dates of the outages, and keep receipts if you have to travel to the bank - this log will help to support a complaint if you've been left out of pocket.
Complain to your bank
Complain to the bank and ask for compensation to cover the losses and ask them to take all steps to put the situation right.
In your complaint, make sure you include:
Who you spoke to at the bank during the outageThe losses you suffered as a result of the outageWhat you want the bank to do to put things rightUnhappy with the bank’s response? Go to the FOS
If you’re unhappy with how the bank dealt with your problem, you can contact the Financial Ombudsman Service (FOS). The FOS can usually get involved 15 days after you’ve raised your concerns with the bank – and sometimes even sooner.
It official powers to help customers solve problems with their banks when people can’t agree and will look at the facts, ask questions and make a decision on the fairest course of action.
