The non-equilibrium ageing behaviour of the three-dimensional and four-dimensional critical Ising spin glass is studied for both binary and Gaussian disorder. The same phenomenology of the time-dependent scaling as in non-disordered magnets is found but the non-equilibrium exponents and the universal limit fluctuation-dissipation ratio depend on the distribution of the coupling constants.
