Dear Customer,

Our dark fiber supplier Eurofiber, will do a Service-Affecting maintenance KA-NL-508678.

Location: Kolo NL1, Dronten, NL – GlobalSwitch, Amsterdam, NL
Service Type: Dark fiber

Start: 2025-09-18 23:00:00 CEST
End: 2025-09-19 07:00:00 CEST
Duration: 8 hours
(due to the estimated amount of work, our contractor needs an extended maintenance window to be able to properly complete the work)

Reason: Preventive maintenance work is carried out to maintain the quality of our fiber network.

This activity will impact the following dark fiber circuits: Kolo NL1, Dronten, NL <-> GlobalSwitch, Amsterdam, NL

Expected Outage: is the expected downtime of DWDM channels from the Kolo NL1, Dronten to GlobalSwitch, Amsterdam only.
