A disappearing warehouse.

A software glitch caused the warehouse to vanish, not from physical view, but from the watchful eyes of a well-known retailer's automated distribution system.

"For three years, nothing arrived or left," Charette wrote. "Employees were still getting their paychecks, however, because a different computer system handled the payroll. When the software glitch finally came to light, the merchandise in the warehouse was sold off, and upper management told employees to say nothing about the episode."
