Ahold Delhaize shut down the websites of its retail banners on Sunday, October 11, 2026, after a cybersecurity incident in its network, suspending online grocery ordering and deliveries across its U.S. and European operations.

The Zaandam, Netherlands-based company confirmed the move on Monday, October 12. Taken offline were the websites of U.S. banners Food Lion, Hannaford, Stop & Shop and both Giant Food banners. The outage also reached the company's European properties, including Albert Heijn, Delhaize, Etos, Gall & Gall and bol.com.

"Our teams are taking steps to assess and mitigate the issue. This includes taking some systems offline to help protect them," the company said in a statement. "Protecting our infrastructure in the best interest of our customers, associates and partners is a top priority."

A spokesperson for the company's U.S. operations declined to comment further.

What stays running and what does not?

All stores remained open, the company said. But the digital layer that increasingly drives grocery economics did not.

According to a report on Dutchnews.nl, personal loyalty-based discounts and app-linked savings programs were suspended. Electronic shelf labels (digital price tags updated from central systems) might display last week's prices, meaning prices at the register could differ from prices shown at the shelf. Those labels are in limited use in U.S. stores but more widely deployed at European banners.

For a retailer that has pushed customers toward loyalty apps and personalized pricing, the suspension removes a lever that supports basket size and repeat purchase frequency. It also raises a shelf-edge integrity problem: a price mismatch between label and register is a direct customer-trust and compliance risk, however temporary.

How does this fit the wider pattern?

The incident follows a wave of attacks on European food retail. On the same Sunday, a separate cyberattack caused refrigerators at hundreds of supermarkets in France to heat to roughly 50 degrees Celsius (about 122 degrees Fahrenheit) for about six hours, producing widespread food losses, according to reports.

Two British supermarket chains, Marks & Spencer and Co-op, were also recently hit with cyberattacks that forced them to shut down their digital operations.

Ahold Delhaize itself is a repeat target. The company disclosed last year that a November 2024 cyberattack affected more than 2 million customers at its U.S. stores, disrupting deliveries, payment processing, pharmacies and the online portals of its various banners. Last June, another major cybersecurity breach hit the operations of grocery distributor UNFI (United Natural Foods Inc.), the primary supplier to Whole Foods and a key wholesale link in U.S. natural and organic distribution.

What does this change for suppliers and distributors?

The immediate exposure is transactional. With online ordering and delivery suspended at every major Ahold Delhaize banner, suppliers lose their digital shelf and e-commerce replenishment signals until systems return. Pharmacy and payment disruptions after the 2024 incident suggest order-to-cash cycles can degrade in ways that outlast the outage itself.

The longer-term question is channel economics. Grocery retail has concentrated digital ordering, loyalty pricing and shelf-edge labeling onto shared network infrastructure. Each incident in this sequence — Ahold Delhaize 2024, UNFI June, M&S, Co-op, the French refrigeration attack and now Ahold Delhaize 2026 — demonstrates that a single network compromise can switch off revenue streams spanning millions of customers at once.

Ahold Delhaize has not disclosed when websites, delivery booking or loyalty pricing will resume, nor whether customer or supplier data was affected. The company said its assessment and mitigation work continues.
