By means of parallel tempering Monte Carlo simulations we find strong evidence for a finite-temperature spin-glass transition in a system of diluted classical Heisenberg dipoles randomly placed on the sites of a simple cubic lattice. We perform a finite-size scaling analysis of the spin-glass susceptibility, χ\rm SG, and spin-glass correlation length, ξL. For the available system sizes that can be successfully equilibrated, the crossing of ξL/L versus temperature is strongly affected by corrections to scaling and possibly by a short-length scale ferromagnetic spin blocking. Similarly to many studies of different three dimensional spin-glass systems, we do not find a crossing of the spin glass order parameter Binder ratio.
