Many systems in nature cannot equilibrate with the environment giving rise to
novel and surprising behaviour including memory, aging and nonlinear-dynamics.
Glasses[1-11], interfaces[12] and fractures are some examples[13]. Unlike their
equilibrated counterparts, the dynamics of out-of-equilibrium systems is generally
too complex to be captured by simple macroscopic laws[1]. Here we investigate a
system that straddles the boundary between glass and crystal, a Bragg glass[14,15],
formed by vortices in a superconductor. We find that the response to an applied
