Downtime

Shoppers at a hundred Tesco stores were forced to stand in long queues because, you guessed it, they were upgrading the software on the checkout tills in 100 locations. Tesco said the glitch affected only a minority of stores, but clearly that it not where its computer woes ended. Tesco was fined £31,000 for selling out-of-date food in three stores. Perhaps an upgrade of the company's stock tracking system would be in order.
