Looks like pretty much all BT lines blipped. Investigating.
As expected lines came back quickly, but we need to find why BT blipped.
Reports of one Be line "wobbling" for a few seconds but not losing connection may be a side effect as Be Lines seem generally unaffected by this. Look BT specific.
Lines come back spread between the LNSs so some lines will have had a second brief blip while moved to the other LNS.
