We have studied the low-temperature ac magnetic susceptibility of the diluted spin ice compound ${\mathrm{Dy}}_{2\ensuremath{-}x}{M}_{x}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$, where the magnetic Dy ions on the frustrated pyrochlore lattice have been replaced with nonmagnetic ions, $M=\mathrm{Y}$ or Lu. We examine a broad range of dilutions, $0\ensuremath{\leqslant}x\ensuremath{\leqslant}1.98$, and we find that the $T\ensuremath{\sim}16\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ freezing is …
