Analysis of the light from SN1987A suggests this has not happened. By observing light traversing two paths to reach earth, we can work out how far away the supernova is without relying on a particular value of c, and then work out what c must be out there.

This still makes some assumptions on the speed of light, but it would have to vary in a very specific way to give this same effect.
