Ahold Delhaize keeps its stores open while some systems stay offline after a cyber incident

The company's own wording sets the frame. It called the event a "cybersecurity incident" ^[1] and said taking systems offline was done "to help protect them" ^[2]. That makes at least part of the outage a containment step, and containment ends when the company judges the systems safe to restore.

The reports reach six banners in three countries ^[12]. Albert Heijn, Etos and Gall & Gall are named in the Netherlands and Delhaize in Belgium ^[4], with Stop & Shop and Food Lion in the United States ^[3][5]. We think that spread points to shared services behind the brands, though the company has not described its architecture. The banner-level detail is BleepingComputer's reporting, drawn in part from a memo shared by Food Lion employees.

Scale sets the stakes. Ahold Delhaize runs more than 9,400 stores ^[8] and serves around 60 million customers a week ^[10]. On 2024 net sales of over $104 billion ^[11], that averages at least $285 million a day ^[13]. Stores are open, so the figure shows how much passes through the company's systems. It is not a loss estimate.

For partners, the evidence is narrow. The company said "Protecting our infrastructure in the best interest of our customers, associates and partners is a top priority," ^[6] but the specific partner-facing failure on record is order handling at Food Lion. We'd expect third parties that exchange orders with these platforms to look there first, before treating the whole group as down.
