   21 septembrie 2026 12:16 BST Identificat - Am identificat o întrerupere a unei mici selecţii de servicii către conexiunile publice din amonte din cauza unuia dintre routere noastre de margine resetarea automată a NP. Resetarea automată elimină eroarea identificată de router, dar va fi determinat traficul să redirecționeze către o cale diferită în timp ce ruta nu era disponibilă. Evenimentul şi-a revenit deja complet şi investigăm cauza. În acest moment nu ne aşteptăm la alte întreruperi, deoarece resetarea automată va fi eliminat orice erori. 21 septembrie 2026 15:39 BST Rezolvat - Nu am mai văzut alte dovezi de erori care să apară pe NP ca atare, consideră că sistemul este stabil. Suntem în contact cu a treia parte în ceea ce privește evenimentul pentru investigații suplimentare. Vom continua să monitorizăm acest dispozitiv îndeaproape.

   14 iulie 2026 14:08 BST Programat - CustodianDC planifică întreținerea esențială a fibrelor negre pe propria noastră infrastructură la Goswell Road (GOS), care va avea un impact asupra legăturii noastre cu fibre întunecate de la Goswell Road (GOS) la Dartford (DA2). În timpul acestei întreţineri, vom avea perioade de linişte reduse, deoarece hardware-ul şi patch-urile sunt migrate. [Layer-3 IP Transit Services] Reţeaua noastră principală IP Transit redirecţionează automat toate serviciile protejate atunci când se detectează o ruptură de fibre şi aduce fibra eşuată înapoi în funcţiune doar după ce a fost stabilă şi fără erori pentru o perioadă de timp. Ca atare, toate serviciile Layer-3 vor avea posibile întrerupătoare de cale la începutul și la sfârșitul acestei lucrări, în funcție de calea de destinație selectată, cu potențiale modificări ale latentității la anumite destinații. Nu se preconizează nici o perturbare semnificativă a serviciilor IPT în orice locație. [Layer-2 MPLS/VPLS Services] Serviciile standard Ethernet care au o cale între GOSDA2 vor experimenta o întrerupere. Serviciile Ethernet protejate care au o cale între GOSDA2 pot vedea un comutator/redirecționare în timpul acestei lucrări. Serviciile Diverse Ethernet care includ o cale între GOSDA2 pot vedea pierderea unui membru; nu se așteaptă întreruperi paralele ale ambelor furaje. [Servicii de lungime] Serviciile dintre GOSDA2 vor suferi o pană de curent. Această întreținere a fost programată sub bilet: [CDC-ID: #0315111] 25 iulie 2026 09:00 BST Activ - de întreținere programată începe. 25 iulie 2026 20:00 BST Completat - Întreținerea programată este completă.

   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.

   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.
