On September 22, 2017, the IceCube Neutrino Observatory has observed for the first time ever an extremely high-energy neutrino in spatial and temporal coincidence with a  gamma-ray flaring blazar, TXS 0506+056. Following the original IceCube alert, the source has been observed by several telescopes in a broad wavelength band. Triggered by these detections, archival IceCube events have been analyzed in order to better understand the physics and the time-evolution of the object. In this talk we report on the combined result from all analyses published lately in two Science articles.
