I agree that one question is what happened a month ago to change things, and 
it could have been a buggy software update.  However The Moth in the Flame 
programme (b07l1wv4) got corrected a week after broadcast.  It could be that 
it was edited and re-encoded as a result of the edit.  It could also be that 
the Segment not found error was brought to the attention of the BBC or 
Akamai and that was why it was corrected.  The second question is why things 
have got steadily worse over the intervening month, so that now virtually 
all programmes are affected.
