All DISCOVERY CHANNELS MISSING

ALL the Discovery programs have been affected this morning, some have no picture at all, others are heavily pixelated, all other Sky channels OK.
Anyone else the same?

They are quite weak now on SD frequencies now - will also depend on your dish size. I've just checked on 1.4 & 1.9 metre dishes, around 11.30 am and not showing on UK Sky box (though strangely enough I am getting flickers of the signal on a non Sky box, but cannot verify to see channel) - would seem Discovery HD is stronger as that (tested at the same time) is working on both the 1.4 and 1.9 dishes.
