CPK

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

CPK#1443 PHP Security update

A major security vulnerability in PHP was discovered. As of 22 October 2026, our systems have been patched with the new releases. Status as of 2026-10-21 11:00:00 CET 21 October 2026 at 16:00 CEST the PHP team will release new versions, but exploitation attempts are already happening.

CPK#1383 lilo7 access with managed SSH keys

We have updated the authentication process for login server lilo7 (lilo7.science.ru.nl) as part of a test. As of now, your ~/.ssh/authorized_keys file on lilo7 is ignored. This change is designed to prevent bad actors from easily gaining persistent access. The good news is that we can now grant access to lilo7 from outside the previously very restricted IP ranges. To gain access from a new IP range, you will need to provide us with your public SSH key and the IP range you will be connecting from. ...

CPK#1376 Ubuntu PC password files not updated

With the introduction of Ubuntu 24.04 by C&CZ, it turned out that the uids/gids of some users had to be changed because they were too small. This was immediately rolled out on servers, since those are always powered on, but needed a workaround on Ubuntu client PCs. Today it became clear that this workaround ignored new accounts, so first year students and new employees couldn’t use Ubuntu clients. This has been fixed now and all C&CZ managed Ubuntu client PCs in computer labs and the Library of Science have been updated.
