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.

On Wednesday, 18.12.2024 from 17 - 20h it is not possible to guarantee trouble-free operation in the Windows environment. This is due to regular 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: The monthly maintenance work on the appropriate central computers. This requires only in the most unfavourable case the entire period of 3 resp. 2 hours

On Mittwoch, 11.12.2024 between 09:00h and 11:00h the DESY instance of the conference management system Indico (https://indico.desy.de) will not be available.

Please save and finish your work in time and keep presentations you need to retrieve from Indico during this time period on an alternative storage medium (e.g. USB stick or local drive).

The problem is solved since Tuesday, 27.05.2025.

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

Since Tuesday, 01.04.2025, cross-service login via the central authentication service Keycloak does not work as usual.

Normally, logging in once is enough to access multiple services. At the moment, however, this is not possible:
For example, if you log in at https://mail.desy.de or https://xwiki.desy.de, you are not automatically logged in to other services that also use Keycloak.
Currently you need to log in again for each of these other services.

The following web services are affected:

- Indico (https://indico.desy.de)
- DESY Sync & Share (https://syncandshare.desy.de)
- DESY Mail (https://mail.desy.de)
- XWiki (https://xwiki.desy.de)
- Jupyterhub (max-hub and naf-jhub)

We are working on a solution to this problem.

Caused by; Bug in the Login Service (Keycloak)

On Monday, 16.06.2025, the previous printer service v02spool of the Windows terminal server winsaphr[1] will be switched off.

If you only print from winsaphr using the SAP GUI or not at all, you can ignore this information.

If you print from winsaphr from other applications, please carry out a one-time reinstallation of the printer (hr[printer name]) previously used on winsaphr. To do this, please use the new printer service v02spool11.

Instructions for installing new printers on winsaphr can be found on the Desktop of winsaphr or on the following website:
https://it.desy.de/sites2009/site_it/content/e5/e304616/e304647/infoboxContent304649/winsaphr-Druckerinstallation-2025_ger.pdf

If you have any questions, please contact v2hr-support@desy.de

[1] The Windows terminal server winsaphr is used for accessing SAP/HCM, shift planning and exchanging data with V2.

As already announced in the CUC, the Big Blue Button video conferencing software (https://conf.desy.de) will be shut down at the beginning of May 2025.
Accordingly, it will no longer be possible to use the call function in the DESY Chat (chat.desy.de).

Users who require video conferencing service should use ZOOM or DFNConf. Information about these services can be found on the following website:

Since the last update of the Cisco Secure Client for vpn.desy.de <http://vpn.desy.de/> on 7.3.2025, the behaviour of the software has changed.

It can happen that the previously pre-filled “vpn.desy.de <http://vpn.desy.de/>” disappears in the login window of the program. Previously, the Cisco VPN software “remembered” the settings. Since the update to more recent versions, vpn.desy.de <http://vpn.desy.de/> sometimes has to be entered again.

On Monday, 06.01.2025, the name resolution on central Linux installations will be changed to Anycast DNS. Anycast DNS increases the availability and reliablity of name resolutions on Linux.

After the change, only a single DNS server (dns.desy.de - 10.0.0.20) will be configured in /etc/resolv.conf. Additionally, the DHCP templates bios_Linux & uefi_Linux will be changed to Anycast DNS as well.

This change has been announced in the Computer User Committee (CUC).

By the end of the year, the DESY data center and the UCO will be staffed:

- Mon., 23.12.
- Fri., 27.12.
- Mon., 30.12.

Each day from 9:00h; Mon. until 17:00h / Fri. until 15:00h

On the following days the DESY computer center as well as the UCO won't be staffed and thus only the IT on-call service will be reachable on the following days:

- Tue., 24.12. - Thu., 26.12.
- Sat., 28.12. + Sun., 29.12. (Weekend)
- Tue., 31.12. + Wed., 01.01.

From Thursday, 02.01.2025, we will be available again as usual:
https://it.desy.de/help_uco

The acceptance of goods during opening hours and the continuous supervision of critical services are guaranteed. The telephone numbers of the IT on-call service are known to the experiment and machine control rooms as well as the technical emergency service.

On Tuesday, 14.01.2025, the additional protection of e-mail/calendar programs required for security reasons will become mandatory.

In order to be able to continue working with Outlook, Thunderbird or smartphone apps after 14.01.2025, please proceed as described in the following instructions already now:

https://it.desy.de/services/mfa/e_mail_programs/setting_up_an_apptoken

If you have already taken the additional steps to secure your mailbox or only use the website https://mail.desy.de to access your emails, nothing will change for you.

If you have any questions, please contact the IT helpdesk at any time
(e-mail: uco@desy.de / Tel. 5005).

As agreed in the CUC, as of Tuesday, 03.12.2024 access from extern to the Wiki service XWiki (https://xwiki.desy.de) will only be possible via VPN or SSH.
A solution for worldwide read access without login for Spaces which have to be activated explicitly for this kind of access, is currently being developed.

The reason for this measure is to increase the security level of the information provided in XWiki.
