Fast Radio Bursts (FRBs) are millisecond-duration radio flashes, whose large dispersion measures suggest that they originate at extragalactic distances in extremely energetic environments. Once a phenomenon only observed with the Parkes telescope, the discovery of FRB121102 using Arecibo solidified the astrophysical origin of the FRBs. More recently, Arecibo has enabled the astonishing discovery that FRB121102 sporadically produces additional bursts. This immediately rules out the various cataclysmic models - at least for this particular FRB - and is enabling deep, targeted follow-up observations which aim to localize the source to sub-arcsecond precision and to, ultimately, determine its physical origin. I will present our latest understanding of FRB121102 and its relevance for interpreting the FRB phenomenon in general.
