Maybe a clue here, Watson! I have two lines to the Jim hovel. The first existed when I came here; the second is the 'family line'. The new line is measurably faster than the original: they are (according to BT diags) 1 km and 3 km from the exchange. (As the fly crows, 1km is not far off.) Engineer's comment when he visited: 'Ah, one goes by the old route, the new one goes direct'
Hmm.
