Description

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 Maidstone (CDC). During this maintenance, we will have periods of reduced resiliency. This is a part of a wider project to improve existing service between their datacentres which will provide a more resilient network. 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 GOS<->CDC may experience an outage. Protected Ethernet Services which have a path between GOS<->CDC may see a switch/re-route during this work; no significant disruption is expected. Diverse Ethernet Services which include a path between GOS<->CDC may see the loss of one member; no parallel outages of both feeds are expected. [Wavelength Services] Services between GOS<->CDC may experience an outage. This maintenance has been scheduled under ticket: [CDC-ID: #235840]

Description

Engineers from Riello will be performing a UPS service across a number of our systems that supply DF3 and DF4 at our Maidstone facility. Each feed will be worked on separately, and each UPS will be switched to bypass only after the load has been transferred to our generator farms. Although minimal, customers should consider one of their power feeds to be ‘at-risk’ during the period detailed above. Customers with diverse power supplies will only have one feed at risk at any given time, diverse feeds at our facility come from different ATS+UPS chains and are totally independent. This is an at-risk notification only, we do not expect any customer impact during these works.

Description

CenturyLink engineers at Goswell Road will be performing their annual Black Building Test. This activity has been scheduled to validate all documented and authorised processes and procedures pertinent to electrical load transfers. All generator (EPG) and associated back up equipment will be fully tested prior to this maintenance and a call will be placed to the mains supplier to ensure there are no events on their network. During the maintenance please consider all services terminating at GOS to be at risk. Please note that Custodian has two of it's own independent UPS systems at GOS; however if an outage exceeds our UPS runtime then services at GOS may drop.
