  We study the dynamics of 2d spin-ice following a quench from a fully
disordered initial condition (equilibrium at infinite temperature) into its
disordered, ferromagnetic and antiferromagnetic phases. We analyze the
evolution of the density of topological defects and we show that these take
finite density over very long periods of time in all kinds of quenches. We
identify the leading mechanisms for the growth of domains in the ordered phases
and we evaluate the (anisotropically) growing lengths involved in dynamic
scaling.
