At 14:00 The Y.Witless LNS locked up, causing customers connected to it drop and reconnect a few minutes later.
Most lines reconnected by 14:11
Some customers had re-connected to the "U.Gormless" LNS - which doesn't have as much throughput capacity as the Witless LNSs - in order to ease congestion we will manually force some customers to move off U.Gormless by way of a PPP kill - this will force the customer's router to reconnect causing a short outage (typically less than a minute)
The lock-up of Y.Witless was unfortunate as it did cause a disruption to some our customers this afternoon and we had hoped that the work done a week ago to Y.Witless would have helped prevent this hang. However, Y.Witless is out of service and in it's locked state, where our developers can connect to its CPUs and see if they can gain more information.
