Looks like most BT lines when off, possibly not all.
Lines coming back now. Taking a few minutes in some cases.
Some lines will need to be moved to the right LNS.
This means lines will now be on the new timeouts from now.
Status suggest that this was slightly more than half the BT lines. This is specific to BT and not BE lines.
Looking stable, but took a couple of attempts to steer sessions to the right LNS which is another oddity, and perhaps another clue in the mix.
Oddly, and almost certainly unrelated in any way, at 23:32 many of our BE lines dropped.
This does highlight the benefit of having a BE + BT line as they rarely break at the same time!
We'll let you know if we get anything out of BT
In the mean time, most lines will be on new timeouts now.
