Mission details:

• On Oct 29, Eutelsat announced that W3B's propulsion system wasn't working and the satellite was declared a loss. Rumours on www.nasaspaceflight.com suggest an oxidizer leak may have occurred at spacecraft separation, so it's not yet clear if it's a spacecraft or launch vehicle failure.
• Due to a hydrazine fuel leak shortly after release from Ariane stage stranded in GTO and declared a total loss. Solar panels and antenna's not deployed.
• As of Nov 4 the satellite was in a 247 x 35825 km x 2.0 deg orbit and is to be abandoned there.
