All the SD channels just went offair - all showing same genetic caption. Didn't see it happen but was a few minutes ago.

The EPG listings ended at 6am, thats the end of the broadcast day so you'd expect that

When the HD channels were shuffled and brought on air it all happened during the working day as that's when there's staff in to do the changes at all the organisations involved. No point paying lots of people extra to come in overnight

There's a difference though

Sky does that for their channels at. 10-ish 11-ish whatever channel so it's not surprising they did that for the BBC HD channels, while I suppose BBC has a better control over its broadcasting

Sky Sports Racing SD currently off-air.(temporarily I can imagine)

Do you think this is because of what happened this morning? twitter.com

These sorts of changes need co-ordination between the broadcaster and the platforms themselves (and in some cases the satellite operator). So if Sky usually do changes at 10-11 then that's when it'll happen
