I'm with Sky broadband but BT line rental. Mine went off yesterday around lunchtime. I spoke to Sky (surprisingly helpful) and there is a problem in our area. They put through a 'queue jump' issue to BT and promised me it would be resolved by today (Sunday) late afternoon. Fingers crossed on that as when I check BT it comes up with a default of resolution by 3rd May. If I hear any more i will post an update.
