Outages & maintenance

On the night of Wednesday 23 to Thursday 24 September we will be carrying out a firmware
upgrade on the aggregation router for the FttH and FttO interconnect in the Delft and
Pijnacker-Nootdorp regions. The work will take place between 01:00 and 07:00 (CEST).

The maintenance affects all OpenFiber connections on the KPN and Glaspoort networks in
these regions. The expected interruption is approximately 5 minutes within this window.

Once the work is complete, your connection should come back online by itself. If it does
not, you can try restarting your modem and, if applicable, your router.

During the night of 23 to 24 September we will be carrying out a bandwidth upgrade on the connection supplying the CPO apartment complexes on Nieuwe Gracht. The work will take place between 01:00 and 07:00 (CEST) and is expected to take no longer than 15 minutes.

During this brief interruption your internet connection will be unavailable. It should come back automatically once the work is complete; if it does not, you can try restarting your modem and, if applicable, your router.
