On a direct course/track to GARIC. All of a sudden the aircraft began to roll left. Disengaged autopilot in order to stop roll. At that time; it wasn't determined to be a flight control problem or navigation problem. Regained control of the aircraft and attempted to reestablish navigation to GARIC; but aircraft wouldn't hold course. Received a GPS downgrade message. Deselected GPS Navigation; forcing the navigation to radio updating. Reported the incident to JAX Center; and they acknowledged that they had received other reports of same. Later; ADSB faults were experienced. Other aircraft reported same. The GPS resumed normal operations as well as ADSB.
