Just saw a thread about this on another board.
Season 5 of Doctor Who and season 4 of Torchwood (ie Miracle Day) are now on Netflix Ireland and so presumably Netflix UK also.
Also added are the rest of the David Tennant specials.
Odd that it should happen now, as most of Netflix's updates seem to happen on the first of the month.
The iPlayer iPad app seems to be unaffected as yet.
