We’ve seen some sessions drop (on ADSL and FTTC/FTTP connections|) following an unexpected port reboot on one of our main switches here.
Most sessions have automatically re-connected but if your line is failing to come back as expected, it may have a stale session which needs to be cleared down. To do this, please power-down your router for 15/20 minutes and then attempt to re-connect.
This should bring you back on-line but please raise a fault with support here in the normal manner if you’re then still having problems.
