Maintenance breaks are absolutely necessary to keep Clash of Clans playing smoothly, and free of bugs. To make sure this interruption doesn't cause you to lose any precious boost time you've paid for, the game now automatically pauses any active boost that are interrupted by a service break.

The pause applies to Spell Factories and Heroes, along with Dark and regular Barracks. Boosted resource collectors will keep churning out precious gold and elixir even during a maintenance break.

You can resume the boost at your convenience. Simply tap on the paused building, which will have a red glow around it, and tap the 'Resume' button.
