Dark fiber maintenance of our supplier “Relined” PA-261002

Dear Customer,

Our dark fiber supplier ”Relined” will do a Service-Affecting maintenance PA-261002.

Location: Serverius DC1, Dronten, NL – Nikhef, Amsterdam, NL
Service Type: Dark fiber

Start: 11-12-2025 00:00:00 CET
End: 11-12-2025 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: Serverius DC1, Dronten, NL <-> Nikhef, Amsterdam, NL

Expected Outage: is the expected downtime of DWDM channels from the Serverius DC1, 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.
