Scheduled Maintenance

Schedule

January 23, 2021 20:00 - January 24, 2021 04:00 GMT

Components

MPLS/VPLS/L2VPN, DWDM/Wavelength

Locations

BYF, CDC, GS2, MER, GAT, GOS, SOV, THN

Description

Custodian engineers will be upgrading and replacing core DWDM optical transport equipment across several sites under tickets #235506 and #235507. This is to enable additional capacity by increasing the number of 100G services available to customers, whilst also enabling 200G and 400G wavelength solutions in parallel. [Scope] This first notification is for essential upgrade works which will impact services TRAVERSING the links between Maidstone and Telehouse North. Affected services will be offline for 2 separate periods during the window, each is expected to last up to 45 minutes while engineers remove and replace DWDM equipment on our dark fibre network. Any rollback requirement will extend this time. [Impacted Services] Wavelength services traversing the link between CDC and THN will be impacted. For Diverse wavelength services, only one service will be impacted during this window. Unprotected Layer-2 Services taking this path between CDC and THN will be impacted. Protected Layer-2 Services will see a brief sub-second loss whilst they reroute. Diverse Layer-2 Services will see an impact only on one of the two interfaces. IP Transit services are not directly impacted, but may see path/latency changes during core convergence events. [Additional Clarifications] Direct services from CDC to GOS, or directly between other London PoPs that do not travel via CDC are not impacted by this maintenance. Services traversing the PoPs listed above, for example, going to 4D in Byfleet or Gatwick via THN, will be impacted by this maintenance.
