Unlike the higher-dimensional cases, in the simplest approach all finite-energy excitations of AdS\_2 x S^2 are suppressed. Surviving zero-energy configurations are described. These can include tree-like structures in which the AdS\_2 x S^2 throat branches as the horizon is approached, as well as disconnected AdS\_2 x S^2 universes. In principle, the black hole entropy counts the quantum ground states on the moduli space of such configurations. In a nonsupersymmetric context AdS\_D for general D can be unstable against instanton-mediated fragmentation into disconnected universes. Several examples are given.
