Ok I got a good question for you Leewong.
Light is the "fastest" thing in the known universe right?
But if the sun went supernova the light would take eight minutes to reach us on earth before we knew that it had went supernova.
But gravity would cease immediately.
So is gravity being a force, faster than light?
Sorry these are the things that I think of when I'm two glasses in to a bottle of Maker's

The gravitational wave would propagate at the same speed as light would. The affects of both would be observed simultaneously. Gravity would not shut off before the lights went out.
"The speed of gravitational waves in the general theory of relativity is equal to the speed of light in vacuum, c.[1] Within the theory of special relativity, the constant c is not exclusively about light; instead it is the highest possible speed for any interaction in nature." -wikipedia
