One of our LNSs had an issue today, lines blipped and reconnected automatically. Graphs are lost from before the incident, and usage for the hour up to the incident will not have been metered/billed.
We have some clear ideas what caused this and it is being investigated.
This only affected one of the three live LNSs.
Note we cleared some of the affected lines back to the original LNS at 9pm causing a PPP reconnect.
