Abstract
For all dimensions we prove there exist solutions to the focusing cubic nonlinear Schrödinger equations that blow up on a set of codimension two. The blowup set is identified both as the site of concentration and by a bounded supercritical norm outside any neighborhood of the set. In all cases, the global norm grows at the log-log rate.
