Is "dark flow" real or error?

Not dark energy or dark matter -- I mean the supposed motion of galaxy clusters toward a patch of sky between Centaurus and Vela found in 2008 (in the CMB). I remember there being dispute it was a calculation error ... is there a consensus on that now? Real phenomenon or mistake?

    I have just watched a programme on it and still no-one knows exactly what this is. It first came to mind due to the observations of clusters of galaxies moving irrationally towards a single point. However, apprently,if it exists, then there would have to be another universe outside ours for this to be possible.!!!!
