Unique Design B.V. - Scheduled maintenance by Fusix on redundant upstream fiber path – Maintenance details

Our network carrier Fusix Networks will carry out scheduled maintenance on part of the dark fiber connection between euNetworks in Amsterdam and the EFCI Rotterdam, Nedzone, and Brabant data centers.

This maintenance is scheduled from Wednesday 25 February 2026 at 23:00 CET until Thursday 26 February 2026 at 02:00 CET.

During this window, one of our redundant upstream routes may be temporarily affected. BGP sessions to the euNetworks core router may briefly go down, virtual leased line circuits on that path may be interrupted, and VRRP may temporarily fail over to the backup core router in NIKHEF Amsterdam.

The expected work duration is no more than 30 minutes within the maintenance window. Because the infrastructure is redundantly connected, we do not expect a full service interruption, but there may be a temporary loss of redundancy.

No action is required on your side.
