What is channeling in espresso? Signs and practical checks

Channeling in espresso is uneven water flow through the coffee bed: some paths carry more flow than surrounding areas. It can make extraction less consistent, but a spray, a pale patch or one unusual shot does not identify the cause by itself. Check the recipe, basket condition and puck preparation before deciding which variable to change.
