One of our third-party providers has advised that they need to perform maintenance at Telehouse North (THN) which has the potential to impact our Dark Fibre link from Telehouse North (THN) to Maidstone (CDC).
This maintenance is to be considered as "at risk".
[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 THN<->CDC may experience an outage. Protected Ethernet Services which have a path between THN<->CDC may see a switch/re-route during this work; no significant disruption is expected. Diverse Ethernet Services which include a path between THN<->CDC may see the loss of one member; no parallel outages of both feeds are expected.
[Wavelength Services] Services between THN<->CDC may experience an outage.
This maintenance has been scheduled under ticket: [CDC-ID: #242408]
