Service interruptions

A CPK is C&CZ’s way of reporting a problem or service interruption. Follow the mailing list or RSS feed, and check the service interruptions page for live status updates.

A CPK is how C&CZ reports a problem or service interruption. We publish one when something goes wrong, when we need to do planned maintenance, or when we want to let you know about something that affects the services we run.

Note

What’s a CPK? CPK is short for the Dutch C&CZ Probleem Kaart — C&CZ problem card. The name is simply how we’ve always done it, and it has stuck with us ever since.

How to follow CPK messages

CPK messages are first sent to the CPK mailing list — you can (un)subscribe there. You can also follow the service interruption messages via RSS.

When a CPK takes longer to resolve, we publish updates on the service interruptions page.

University-wide interruptions

For Radboud University-wide service interruptions, see meldingen.ru.nl.
