Custodian’s Networking team have identified a hardware fault on one of our edge router platforms, we have been monitoring this device since its last reload and have decided to replace the line card on this router to resolve the NP fault.
From our findings so far, this specific NP issue only occurs after a few or more weeks after a reset or reload of the NP. Given this, we are expecting there to be no further automatic NP reloads that will occur between today (12/12/25) and this maintenance window.
Due to this being an edge router, the works to replace this hardware will not be service impacting to customers as we will cleanly remove it from service before replacing the hardware.
If any impact to services were to be identified, these would only be due to network path re-routes round our core as the unit is cleanly decommissioned and then recommissioned on to its new hardware.
Given the above, this is an at risk notification only. We do not expect customers to notice any impact to services.
This maintenance is logged under [CDC-ID: #254870]
