Scheduled - We have identified a non-service impacting fault on the DWDM chassis in the Wakefield data centre (DC-3) which supports the dark fibre to Northampton data centre (DC-4).
Engineers need to perform intrusive maintenance on the chassis to carry out diagnostics and replace hardware if necessary.
During this maintenance DWDM based services between Wakefield and Northampton will experience service interruption.

Date : Wednesday 25th 00:00 – 05:00

Standard Internet and MPLS Services provided from Wakefield data centre DC-3 will operate at reduced resilience. These services will automatically be re-routed via alternative paths.
DWDM based services will be at risk for the full maintenance window, downtime will occur this is expected to be less than 30 minutes in total. Although there may be more than one downtime occurrence during the window.

Engineers will be on site from midnight preparing for the work with service impacting changes starting at 01:00.

Scheduled - On Sunday 22nd April 2018 @ 08:00 Node4 Engineers will be carrying out work to upgrade the firmware on the customer shared NetScalers located on the cloud platform at Slough. We expect the work to take between 30 minutes and an hour and will follow these steps: upgrade secondary appliance, reboot, once it is up check to make sure it has synchronised with the primary, fail-over the appliances and perform the same steps on the remaining appliance. There is no expectation of downtime and in the event there is an issue the appliance will be reverted back to the current firmware version. Most customers will not be effected by this change only those that use Node4's shared NetScaler platform for load balancing their web servers.
