The DFN Association (Association for the Promotion of a German Research Network) has informed us that the eduroam service (Easyroam) is currently experiencing disruptions.

Network connections via eduroam cannot be established reliably at this time.

The DFN is working on a solution; no further information is available at this time.

Trouble caused by: Unknown

On Friday, November 7, 2025, between 9 a.m. and 1 p.m., a planned power outage will take place in Zeuthen in order to switch back from generator power to the regular local power grid.

During the switchover, there may be brief interruptions to the power supply and associated services.

All services should be available again from 1 p.m. onwards.

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

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.
