    The paper concerns the radially symmetric Cauchy–Dirichlet and Cauchy–Neumann problems for the porous media equation in the domain comprising the spatial variable and the temporal variable $t$ in the exterior of the unit ball in $\mathbb{R}^n$ and the bounded interval $(0,T)$, respectively. The subject of study is the behavior of solutions when the initial data are compactly supported and the boundary data become unbounded as $t\uparrow T$. Necessary and sufficient conditions for localization, estimates of the size of the blow-up set, and a number of allied results are obtained.
