How long could Britain’s food supply function without the internet?

Britain would not run out of food the moment the internet disappeared. Farms, warehouses, vehicles, shops and workers would still exist. The more difficult question is how quickly coordination, ordering, payment and visibility degrade.

Modern supply chains respond to demand through information. Stock positions, delivery schedules, warehouse systems and retailer decisions turn physical capacity into available food. When that shared picture fragments, the challenge is not only quantity. It is knowing what exists, where it is and where it should go next.

A seven-day scenario therefore needs to distinguish shortage from distribution failure. Shelves can empty locally while goods remain elsewhere in the network. Public behaviour then becomes part of the system: extra buying changes the very demand signals operators are struggling to read.
