Currently, there are various issues when printing via cups.desy.de or desyguestprint.desy.de from Linux and macOS.

Linux and macOS:
- Separator sheets are not being printed.
- Print settings selected in the print dialog may sometimes be ignored.
- The paper tray (for different paper types such as colored/white, A3/A4, etc.) is not always selected correctly.

macOS:
- Print jobs may occasionally fail to print.

If you encounter these issues, please switch to a Windows device if possible or use the Windows Terminal Server winterm.desy.de.

We are working on solving these issues.

Trouble caused by: Technical Problems after changes in the infrastructure

Currently there are sporadic issues with connecting to IT services routed through the central load balancer (F5). Affected services may experience significant slowdowns or timeouts, making them intermittently unavailable.

Connection problems have been observed particularly with the following services:

- Sync & Share with Nextcloud Talk
- Indico
- Zimbra web interface (https://mail.desy.de)
- LDAP authentication service
- Single Sign-On service Keycloak

We are working together with the manufacturer of the load balancer system to resolve these issues.

Trouble caused by: Problems in the load balancing system F5

The maintenance has been finished.

-----------------

Today, Friday, 19.06.2026, there will be a short interruption in the availability of the Windows Terminal Server winterm.desy.de. Existing sessions will not be terminated and will still be available after the maintenance.

Maintenance caused by: Switch to another server

On Donnerstag, 18.6.2026 from 08:00 h to 16:00 h maintenance work will be carried out on the central e-mail service (mail.desy.de).

During the maintenance period there will be interruptions in access via the web interface (https://mail.desy.de). Access with Outlook or Thunderbird will be limited, too. Shared folders and calendars may not be accessible for a short time.

When composing emails, please regularly back up the current status in the Drafts folder to avoid data loss.

Maintenance caused by: Installation of critical security updates through the upgrade of Zimbra to the latest version

On the second Friday of every month, the monthly Windows updates are released. Please install them on your DESY Windows devices as soon as possible to ensure that they are up-to-date and secure.

To do this, connect your Windows device to the internal DESY network after the updates have been released. Use VPN if you are extern. When prompted or at the end of the day, restart or shut down your Windows device.

Seven days after the release of the updates, a forced restart of the computers will take place if this has not taken place in the meantime.


Hint:
On Wednesday which follows the release of the updates from 17:00 to max. 20:00, trouble-free working in the Windows environment cannot be guaranteed due to the monthly maintenance work on the central Windows servers.

It is recommended to log off or shut down DESY Windows devices on Wednesday before the maintenance starts. You should also log off from public Windows systems (terminal servers) beforehand.

Maintenance caused by: Windows updates and the monthly maintenance work on the corresponding central computers

Regular Maintenance Slot: TSM (ADSM) backup server

Time: each Tuesday, 12:00 pm - 8:30 pm
Systems: all

Impact: The TSM backup servers will be partly down. It will not be possible to restore files on the central Unix or Windows systems from backups made by the TSM.

An apology must be made in advance: It is always possible that things do not work as planned. Therefore the given ending times may not be kept as promised.

Maintenance caused by: Update of the Service

Currently, the Start menu is not displayed on the terminal server winterm.desy.de.

The cause of the issue is currently unknown, so a solution is not expected in the near future.

Caused by; Unknown

When digital security certificates are used in emails sent via Microsoft Outlook, it may occur that emails are sent incomplete.

Based on current findings, the issue arises after messages have already been saved as drafts. Starting from the second modification after the initial creation of a draft, changes are no longer saved in the message.

Please use one of the following workarounds to bypass the issue:

- Send emails via https://mail.desy.de
- Do not sign emails in Outlook with digital security certificates

The issue has been reported to the vendor for a problem solution.

The following two DESY standard PCs are currently no longer available from stock:

- Dell Pro Micro Lite QCM1250 U5/16/512 (Micro-PC)
- Dell Pro Micro Plus QBM1250 U5/16/512 (Micro-PC)
- Dell Pro Max 16 Premium MA16250 (CAD-Notebook)
- Dell Precision 5860 Tower (DESY Standard PC Work 04.25)

If these devices are requested via the AMS, significantly longer delivery times must be expected. Depending on the outcome of the ongoing price negotiations, these devices may also no longer be available at the previous price.

Caused by; General shortage of RAM, hard drives, and SSDs on the market (see: https://www.techbook.de/pc-mac/hardware/dram-speicher-preis)

In this storage service, the default settings for permissions when sharing a directory may lead to unplanned behaviour, which we would like to draw your attention to with this information.

The behaviour is based on the fact that the default settings also include the right to delete. The result can be that data becomes inaccessible to the person who shared the data if one of the persons with whom the data was shared moves it; this corresponds to copying it to the target folder and then deleting it in the source folder.
The files and directories are not lost, but are now in the directory tree of the person who moved them.

To work around this issue until it is fixed, the recommendation is not to move any data that has been shared with you via Sync & Share. Persons already affected will be informed directly.

A support request is in progress at the manufacturer.

If you have any questions, please contact uco@desy.de.
