We did some work yesterday to try and ensure we are correctly tracking lines being up and down. If ever there is any problem with RADIUS accounting this can get out of step. It is meant to sort itself out automatically, but there seemed to be some cases where that was not quite right. Unfortunately the change led to lots of up/down emails, texts, and tweeks over night. We think we have managed to address that now, and will be monitoring during the day.
We believe this is all sorted now.
