The Whole Earth Blazar Telescope has been monitoring the quasar-type blazar 3C 454.3 since its extraordinary outburst of spring 2005, which was detected from the near-IR to the X-ray frequency range. Soon after an outburst was observed at mm and later on at cm wavelengths. The source underwent a period of quiescence in the 2006-2007 observing season, during which optical-UV spectral energy distributions showed evidence of both the little blue bump due to line emission from the broad line region and the big blue bump due to thermal emission from the accretion disc. In May 2007 observations by the XMM-Newton satellite revealed that the source was brightnening at high energies, and indeed a new optical outburst was observed in July-August 2007. This triggered observations by the AGILE satellite, which detected the source in its highest gamma-ray state ever observed. A new phase of intense optical activity was observed in November 2007 - January 2008, which was characterized by many episodes of very fast variability. In this period AGILE made a new detection.
