Dark fiber maintenance of our supplier “Relined” PA-675001

Dear Customer,

Our dark fiber supplier ”Relined” will do a Service-Affecting maintenance PA-675001.

Location: KoloDC NL1, Dronten – Nikhef, Amsterdam
Service Type: Dark fiber/DWDM channels

Start: 03-09-2026 00:00:00 CEST
End: 03-09-2026 06:00:00 CEST
Duration: 6 hours.

Reason: Due to reconstruction work, commissioned by local authorities, Relined is forced to relocate part of its network. This action will result in a temporary interruption of service.

This activity will impact the following dark fiber circuits: KoloDC NL1, Dronten <-> Nikhef, Amsterdam

Expected Outage: is the expected downtime of DWDM channels from KoloDC NL1, Dronten to Nikhef, Amsterdam only. No expected outage for IP transit service; other dark fibers will automatically take over the data traffic, but there is a slight chance of high latency and short-term packet loss during the time of rebuilding routing tables.

We apologize in advance for any inconvenience this might cause.
