Refrigeration systems had failed at commissaries at U.S. military facilities this summer, spoiling food and temporarily limiting supplies.

In October, freezers malfunctioned at hundreds of grocery stores in France in what officials called a cyberattack.

On Nov. 2, retailers in at least seven more European countries reported problems with refrigeration units.

A week later, French officials accused Iran of orchestrating the attack.

At least five other U.S. military bases abruptly switched into heating or defrost modes overnight in late August 2026, ruining entire inventories of frozen food.
