   21 de septiembre de 2026 12:16 BST Identified - Hemos identificado una interrupción a una pequeña selección de servicios a las conexiones públicas aguas arriba debido a uno de nuestros propios routers de borde automáticamente reajustando su NP. El reajuste automatizado despeja la falla que el router identificó pero habrá causado que el tráfico vuelva a recorrer un camino diferente mientras que la ruta no estaba disponible. El evento ya se ha recuperado completamente y estamos investigando la causa. En este momento no esperamos ninguna interrupción adicional ya que el reset automático habrá borrado cualquier error. 21 de septiembre de 2026 15:39 BST Resolved - No hemos visto ninguna evidencia adicional de errores que aparecen en el NP como tal creen que el sistema es estable. Estamos en contacto con terceras partes en relación con el evento para nuevas investigaciones. Seguiremos monitoreando este dispositivo de cerca.

   14 de julio de 2026 14:08 BST Programado - Custodio-PD están programando el mantenimiento esencial de fibras oscuras en nuestra propia infraestructura en Goswell Road (GOS) que impactará nuestro enlace de Dark Fibre desde Goswell Road (GOS) a Dartford (DA2). Durante este mantenimiento, tendremos períodos de resiliencia reducida a medida que se migra el hardware y el parche. [Layer-3 IP Transit Services] Nuestra red de transit IP central reenvia automáticamente todos los servicios protegidos cuando se detecta una ruptura de fibra, y trae la fibra fallida de nuevo al servicio sólo una vez que ha sido estable y libre de errores durante un período de tiempo. Como tal, todos los servicios de Layer-3 tendrán posibles interruptores de ruta al inicio y final de este trabajo, dependiendo de la ruta de destino seleccionada, con posibles cambios en la latencia a algunos destinos. No se espera ninguna perturbación significativa de los servicios del IPT en ningún lugar. [Layer-2 MPLS/VPLS Services] Servicios Ethernet estándar que tienen un camino entre GOSDA2 experimentará un outage. Los Servicios Ethernet protegidos que tienen un camino entre GOSDA2 pueden ver un cambio/re-route durante este trabajo. Diversos servicios Ethernet que incluyen un camino entre GOSDA2 pueden ver la pérdida de un miembro; no se espera que se produzcan interrupciones paralelas de ambos alimentos. [Wavelength Services] Los servicios entre GOSDA2 experimentarán un outage. Este mantenimiento ha sido programado en el billete: [CDC-ID: #0315111] 25 de julio, 2026 09:00 BST Activo - El mantenimiento programado está empezando. 25 de julio, 2026 20:00 BST Completado - El mantenimiento programado está completo.

   April 9, 2026 11:55 BST Scheduled - One of our third-party providers has advised that they need to perform maintenance at Goswell Road (GOS) which will impact our Dark Fibre link from Goswell Road (GOS) to Dartford (DA2). During this maintenance, we will have periods of reduced resiliency. The 3rd party engineers have identified a damaged section of cable in London that requires replacement, to avoid any further unplanned outages relating to the damage found. Custodian’s networking team will be working closely with the third party at all times. [Layer-3 IP Transit Services] Our core IP Transit network automatically re-routes all protected services when a fibre break is detected, and brings the failed fibre back into service only once it has been stable and error free for a period of time. As such, all Layer-3 services will have possible path switches at start and end of this work, depending on destination path selected, with potential changes in latency to some destinations, no significant disruption is expected to any IPT services at any location. [Layer-2 MPLS/VPLS Services] Standard Ethernet Services which have a path between GOSDA2 may experience an outage. Protected Ethernet Services which have a path between GOSDA2 may see a switch/re-route during this work; no significant disruption is expected. Diverse Ethernet Services which include a path between GOSDA2 may see the loss of one member; no parallel outages of both feeds are expected. [Wavelength Services] Services between GOSDA2 may experience an outage. This maintenance has been scheduled under ticket: [CDC-ID: #255923] April 15, 2026 21:00 BST Active - Scheduled maintenance is starting.

   March 2, 2026 16:09 GMT Investigating - We have identified an interruption to a small selection of services to public upstream connections due to one of our own edge routers automatically resetting its NP. The automated reset clears the fault that the router identified but will have caused traffic to re-route to a different path while the route was unavailable. The event has fully recovered already and we are investigating the cause. At this time we do not expect any further interruptions as the automatic reset will have cleared any errors. March 2, 2026 18:06 GMT Resolved - We have seen no further evidence of errors appearing on the NP as such believe the system to be stable. We will continue to monitor this device closely.

   February 28, 2026 10:12 GMT Monitoring - ME14 has seen a complete loss of 11kV supplies across all feeds due to two separate off-site high-voltage cable faults in the local area of Maidstone. CDC's UPS systems carried the load while all on-site generation started; and then transferred on to load as expected without any interruption to critical infrastructure. There is now an elevated risk level at ME14 while UKPN engineers work to resolve both cable faults and the site remains on local generation. CDC engineering staff on-site are closely monitoring. February 28, 2026 11:06 GMT Resolved - UKPN engineers have completed works to repair the supplies and we have seen the restoration of our 11kV feeders now. The site has cleanly transferred back from local generation to grid without interruption to critical load. The at-risk period is ending now.

   December 12, 2025 15:20 GMT Scheduled - 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] For any queries regarding this window, please contact our NOC December 15, 2025 21:00 GMT Active - Scheduled maintenance is starting. December 16, 2025 06:00 GMT Completed - Scheduled maintenance is complete.
