We describe the recent measurements of bulk flows of unprecedented scale and amplitude. These results are not easily accommodate in the standard ΛCDM cosmology. We study two possible solutions: preinflationary superhorizon sized perturbation and void models of the Lemaître-Tolman-Bondi type and discuss their viability.
