CustodianDC are scheduling essential dark fibre maintenance on our own infrastructure 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 as hardware and patching is migrated.
[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 the 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<->DA2 will experience an outage. Protected Ethernet Services which have a path between GOS<->DA2 may see a switch/re-route during this work.
Diverse Ethernet Services which include a path between GOS<->DA2 may see the loss of one member; no parallel outages of both feeds are expected.
[Wavelength Services] Services between GOS<->DA2 will experience an outage.
This maintenance has been scheduled under ticket: [CDC-ID: #0315111]
