Dear Customer,

Our dark fiber supplier ”Relined” will perform service-affecting maintenance PA-954001.

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

Start: 26-11-2026 00:00:00 CET
End: 26-11-2026 06:00:00 CET
Duration: 6 hours.

Reason: Relined performs maintenance work to maintain the availability and quality of its fiber optic network.

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.
