We show that for any Ricciflat manifold with Euclidean volume growth the
tangent cone at infinity is unique if one tangent cone has a smooth
crosssection. Similarly, for any noncollapsing limit of Einstein manifolds
with uniformly bounded Einstein constants, we show that local tangent cones are
unique if one tangent cone has a smooth crosssection.
