The 180-day Space Telescope and Optical Reverberation Mapping campaign on NGC5548 discovered an anomalous period, the broad-line region (BLR) holiday, inwhich the emission lines decorrelated from the continuum variations. This isimportant since the correlation between the continuum-flux variations and theemission-line response is the basic assumption for black hole (BH) massdeterminations through reverberation mapping. During the BLR holiday, thehigh-ionization intrinsic absorption lines also decorrelated from the continuumas a result of variable covering factor of the line of sight (LOS) obscurer.The emission lines are not confined to the LOS, so this does not explain theBLR holiday. If the LOS obscurer is a disk wind, its streamlines must extenddown to the plane of the disk and the base of the wind would lie between the BHand the BLR, forming an equatorial obscurer. This obscurer can be transparentto ionizing radiation, or can be translucent, blocking only parts of the SED,depending on its density. An emission-line holiday is produced if the winddensity increases only slightly above its transparent state. Both obscurers areparts of the same wind, so they can have associated behavior in a way thatexplains both holidays. A very dense wind would block nearly all ionizingradiation, producing a Seyfert 2 and possibly providing a contributor to thechanging-look AGN phenomenon. Disk winds are very common and we propose thatthe equatorial obscurers are too, but mostly in a transparent state.
