Our network monitoring has alerted us to CPU errors being generated on lns01.dsl.structuredcommunications.co.uk
We have raised a ticket with our hardware vendor for them to investigate and advise. The device remains in operation and routing data as expected, however it should be classed as “at rick” during this time due to the possibility of an unexpected failure.
Other LNSs within the pool are unaffected. Should the above LNS fail then circuits will automatically re-terminate on another device.
UPDATE01 – 11:30
Our hardware vendor has reviewed the logs we have provided and concluded the device could be suffering from a physical hardware issue. We are looking at options on replacing this device.
UPDATE02 – 11:52
While options are being reviewed to replace this device, we have taken the decision to remove it from the active termination pool. This means it will not accept any new PPP connection attemps, however will continue to service existing established ones.
UPDATE03 – 13:05
Replacement hardware has been agreed by the vendor. We will advise of a maintenance window in due course.
The LNS was replaced without issue and is now back in service.
