7월 14, 2026 14:08 BST Scheduled - CustodianDC는 Goswell Road (GOS)에서 어두운 섬유 링크에 영향을 미치는 Goswell Road (GOS)의 자체 인프라에 필수적인 어두운 섬유 유지 보수를 스케줄링하고 있습니다. 이 유지 보수 기간 동안, 우리는 하드웨어 및 패치로 감소 된 탄력성의 기간이 마이그레이션됩니다. [Layer-3 IP 운송 서비스] 우리의 핵심 IP 이동 네트워크는 섬유 틈이 검출될 때 자동적으로 모든 보호한 서비스를 재 노선하고, 한 번만 서비스로 실패한 섬유를 안정되어 있고는 과실은 시간의 기간을 위해 해방되었습니다. 이러한 모든 Layer-3 서비스는 일부 목적지로 인해 선택된 목적지 경로에 따라이 작업의 시작과 끝에서 가능한 경로 스위치가 있습니다. 어떤 위치에 IPT 서비스가 예상되지 않습니다. [Layer-2 MPLS/VPLS 서비스] GOSDA2 사이의 경로가 있는 표준 이더넷 서비스는 정전을 경험할 것입니다. GOSDA2 사이의 경로가 있는 Protected Ethernet Services는 이 작업 중에 스위치/re-route를 볼 수 있습니다. GOSDA2 사이의 경로가 포함 된 Diverse Ethernet Services는 한 명의 회원의 손실을 볼 수 있습니다. 피드의 병렬 정전이 예상되지 않습니다. [Wavelength 서비스] GOSDA2 간의 서비스는 정전을 경험할 것입니다. 이 유지 보수는 티켓의 밑에 예정되었다: [CDC-ID: #0315111] 7월 25, 2026 09:00 BST Active - Scheduled 유지 보수가 시작됩니다. 7월 25, 2026 20:00 BST 완료 - 계획된 정비는 완료됩니다.

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. April 16, 2026 04:00 BST Completed - Scheduled maintenance is complete.
April 8, 2026 12:00 BST Scheduled - One of our third-party providers has advised that they need to perform maintenance between Telehouse North (THN) and DA2. This will impact our Dark Fibre link from Telehouse North (THN) to Dartford (DA2). During this maintenance, we will have periods of reduced resiliency. This particular work by the 3rd party is to remake a badly degraded splicing-case that is leaving circuits vulnerable. 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 THNDA2 may experience an outage. Protected Ethernet Services which have a path between THNDA2 may see a switch/re-route during this work; no significant disruption is expected. Diverse Ethernet Services which include a path between THNDA2 may see the loss of one member; no parallel outages of both feeds are expected. [Wavelength Services] Services between THNDA2 may experience an outage. This maintenance has been scheduled under ticket: [CDC-ID: #255656] April 9, 2026 17:22 BST Completed - This maintenance event has now been cancelled by the third party. Once we are notified by the third party of a new date these will be published under a new maintenance event. For any additional queries please contact our NOC.
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.
January 6, 2026 09:46 GMT Scheduled - Feb 9th 07:00 – Feb 10th 18:00 Our dedicated maintenance team will be working with specialist contractors to undertake significant refresh works to our power infrastructure. These works are essential to maintain the reliance of our power infrastructure and will see increased redundancy and efficiency brought to DF1’s Critical Environment feeds. Between these dates, clients in Data Floor 1 (DF1) fed by UPS Dist 1 will be subject to an extended downtime of a SINGLE feed. Clients with correctly (dual A+B) cabled equipment should not suffer any loss of service but should consider the loss of redundancy during these works. All clients directly affected will be contacted by our Account Management team and our 24 hour team will be on hand throughout the period to offer any assistance required. If you are in DF1, and have not received an email from your Account Manager, please contact our support team. We will of course make every endeavour to keep the single feed downtime to an absolute minimum while maintaining operational safety and the highest levels of H&S. February 9, 2026 07:00 GMT Active - Scheduled maintenance is starting. February 10, 2026 12:08 GMT Completed - The maintenance is now completed.

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.
