Marks & Spencer (M&S) says it has stopped taking online orders as the company struggles to recover from a cyber attack.
Customers began reporting problems last weekend, and on Tuesday the retailer confirmed it was facing a “cyber incident”.
It told the BBC on Wednesday customer-facing systems were back to normal, but some systems remained offline.
Now the firm has entirely paused orders on its website and apps.
“We are truly sorry for this inconvenience,” it wrote in a post on X.
“Our experienced team – supported by leading cyber experts – is working extremely hard to restart online and app shopping.
“We are incredibly grateful to our customers, colleagues and partners for their understanding and support.”
It said its stores remain open despite the issues affecting online ordering.
M&S said on Tuesday it had reported the incident to the National Cyber Security Centre (NCSC).
The National Crime Agency previously told the BBC its officers are working with the NCSC to support the firm.
