The FAA has temporarily grounded the planes in the U.S. after a series of mishaps and malfunctions.
The FAA action applies effectively only to United Airlines, which is the sole domestic carrier currently flying the new airplanes. But other aviation authorities around the world may take similiar actions, per a recommendation by the FAA. There are a total of 50 Dreamliners, Boeing's newest airplane, in active fleets globally.
Here's Boeing's statement on the FAA action:
