The warped braneworld picture introduced by Randall and Sundrum provides new ways of solving long-standing problems in physics, like the gauge hierarchy problem. If the warp factor is different for the time and space components of the metric, new effects may arise. We concentrate on this possibility and show that the speed of gravity may differ from that of electromagnetism, while Lorentz invariance is preserved for the standard model fields. A charged black hole in a 5 dimensional bulk provides the necessary background. Its properties are studied in detail to ensure correct embedding of the brane. Computation of the speed of gravity in this setup is done both perturbatively and numerically. The results are compared with experimental bounds to constrain the parameters of our scenario.
