Once the data network upgrade is complete, the interim switches in the HÜL will be replaced with the latest models. This replacement will result in an outage of the data network (LAN and Wi-Fi) as well as the telephone system (VoIP). The outage is expected to last approximately 2 hours. It is not possible to provide an exact schedule of which connections will be affected and when.

Below is a rough guide by network distribution room:

June 22, 2026, 9:00 AM – 12:00 PM: IT Room 351 June 22, 2026, 12:30 PM – 3:30 PM: IT Room 371 June 23, 2026, 9:00 AM – 12:00 PM: IT Room 313 June 23, 2026, 12:30 PM – 3:30 PM: IT Room 381 June 26, 2026, 11:00 AM – 1:30 PM: IT Room 388A

You can determine which connection is affected by checking the socket label (the room number of the IT room is listed at the beginning).

Barring unforeseen circumstances, the data network and telephone service will be available again after the time window has ended.

[Resolved] [Update] Disruption: Research Cloud - Windows-Server-2025

Tue, 09 Jun 2026 09:19:00 +0200

[Update] A workaround is listed below.

Currently, it is not possible to provision functional Windows Server 2025 VMs in the Research Cloud. Connections via Remote Desktop (RDP) or VMware Remote Console (VMRC) simply result in a black screen.

Until the issue is resolved, the Windows Server 2025 templates have been temporarily removed from the provisioning menu.

Thank you for your understanding.

Workaround: As of now, this is a Microsoft-related issue. A fix is expected to be released shortly via a Microsoft update.

The following workaround can be applied to affected systems. We are working on our VM deployment process so that this workaround will be applied automatically in the future. Workaround:

Connect to the affected VM via the Emergency Console (VMRC) in the Self-Service Portal.
Open Task Manager (e.g., using Ctrl + Shift + Esc).
Click “Run new task.”
Type “powershell.exe” and press Enter to launch PowerShell.
Run the following commands one after the other:

Add-AppxPackage -Register -Path ‘C:\Windows\SystemApps\MicrosoftWindows.Client. CBS_cw5n1h2txyewy\appxmanifest.xml’ -DisableDevelopmentMode

Add-AppxPackage -Register -Path ‘C:\Windows\SystemApps\Microsoft.UI.Xaml.CBS_8wekyb3d8bbwe\appxmanifest.xml’ -DisableDevelopmentMode

Add-AppxPackage -Register -Path ‘C:\Windows\SystemApps\MicrosoftWindows.Client.Core_cw5n1h2txyewy\appxmanifest.xml’ -DisableDevelopmentMode

Then restart the operating system.

After the restart, you should be able to log in via Remote Desktop again without the black screen.

To ensure that your NFS connections continue to function smoothly, please follow these steps:

Ensure that your systems access the NFS server via the DNS name and not directly via the IP address. The DNS name will remain unchanged, so no adjustments are necessary if you are using the DNS name.
If you have manually entered the old IP address in configuration files (e.g., firewalls), please replace it with the DNS name of the server or the new IP address.
You should re-run the NFS mount once during the transition week

[Resolved] [Update] Issue: Exchange, OWA (Outlook Web App) Light, Calendar

Mon, 18 May 2026 15:00:00 +0200

For security reasons, Microsoft has disabled the Light version of OWA (Outlook Web App). Unfortunately, users can no longer switch mailboxes that were previously in Light mode to the normal view, meaning they cannot be used as usual. If this affects you, please contact the Service Desk via e-mail; the Light mode will then be disabled for you by an administrator.

As a result, you will also be unable to access published calendars (e.g. links ending in .html or .ics). When you try to access them, you will receive an error message with the following content:

“This page is currently unavailable. msx.tu-dresden.de is unable to process this request at this time. HTTP ERROR 500”

Thank you for your understanding.

Issue: Published calendars // limitations OWA

Mon, 18 May 2026 15:00:00 +0200

An important security update for Microsoft Exchange is currently affecting the functionality of the Outlook Web App (OWA) webmail application, which is accessible at msx.tu-dresden.de.

Until Microsoft releases further updates, the following limitations apply when using OWA:

Images sent directly within the email body (inline images) may not display correctly or at all in the recipient’s OWA reading pane. As a workaround, send images as email attachments or use the Outlook desktop client to view them.
It is not possible to use published calendars (links ending in .html or .ics). When you click on these links, you will receive an error message with the following content:

This page is currently unavailable.
msx.tu-dresden.de is unable to process this request at this time.

Matrix: Element Desktop is unusable on Windows [UPDATE2]

Mon, 11 May 2026 08:00:00 +0200

[UPDATE2]

Version 1.12.25 of Element Desktop includes a bug fix.

[/UPDATE2]

Currently, some users are seeing the following error message in Element Desktop for Windows:

Event indexer threw an unexpected error

Error: internal error in Neon module: called `Result:unwrap()` on an `Err` value: SendError { .. }`

There is currently no reliable solution to fix this problem. A clean install might help.

Workaround

[UPDATE]

These notifications can be avoided by turning off the message search feature:

Open “All Settings”
Select the “Security & Privacy” tab
In the “Message search” section, select “Manage”
Confirm by selecting “Disable”
If the process takes too long, restarting the Element app may help.

[/UPDATE]

Alternatively, you can use Element Web at matrix.tu-dresden.de. As always, please keep the following points in mind:

Always use more than one active Matrix session, for example on your smartphone.
Enable the key storage and keep the recovery key in a safe place. Verify every new session.
Never clear your browser’s entire cache while you have a Matrix session open.

DDN and Bull will perform a file system check on /data/horse to identify and repair corrupted files. To facilitate this, all HPC clusters (including login nodes, data movers, and data ports) will be shut down. During this time, no access to data in the HPC file systems will be possible:

Downtime Start: May 4, 2026, 17:00 
Expected Downtime End: May 6, 2026, 12:00

To make the most of this downtime, Bull, DDN, and ZIH will also carry out additional global maintenance tasks, such as changes on the network and the NFS file systems, and multiple updates. If the work on /data/horse takes significantly longer than the other maintenance tasks, the clusters Capella, Alpha Centauri, and Romeo will be restarted. These clusters have alternative scratch file systems (/data/cat and /data/quokka), allowing jobs to run there. However, only jobs with the appropriate flag for the required file system (-L cat or -L quokka) will be able to start [1]. (Hint: You might as well include the flags for the required file systems in your scripts today.)

We appreciate your understanding and cooperation as we work to improve the stability and performance of the system.

Maintenance: Shibboleth Service Provider - Update of DFN AAI metadata certificate March 12-19, 2026

Thu, 12 Mar 2026 22:59:33 +0000

The current certificate expires on March 19, 2026. A new certificate https://www.aai.dfn.de/metadata/dfn-aai.pem will be provided by DFN AAI on March 12, 2026. This certificate is used by your Shibboleth Service Provider to verify the signature of the DFN AAI metadata. Specifically for the Atlassian SP - shibd, see here: https://idp.tu-dresden.de/docu/atlassian_sp3.html#idp-metadaten-einbinden.

Is urgent action required? No, the Shibboleth Service Provider (shibd) will still be able to verify the DFN AAI metadata, as the DFN AAI uses the same private key. The validity is not evaluated by shibd. If your service provider (not shibd) or a monitoring process evaluates the validity of this certificate, we recommend obtaining the new certificate from March 12, 2026.

Thu, 12 Mar 2026 07:00:33 +0000

On March 12, 2026, from 8:00 a.m. to 12:00 p.m., we updated the User Principal Name (UPN) of the functional or guest login you use to match its primary email address.

You can use this address to log in to your functional mailbox in your email program. With this change, we are adapting the login name to common Microsoft standards.

As a rule, you can continue working without restrictions. In individual cases, the following effects may occur:

Outlook prompts you to log in again: Please use the primary email address of the function login to log in. If the login name cannot be edited, select “Log in with another user account.”
Outlook signature is missing: Open a sent email, select and copy the signature, then paste it under ‘New Email’ -> ‘Signature’ -> ‘Signatures’ -> ‘New’, and specify at the bottom when it should be used. Confirm by clicking ‘OK’.
Thunderbird requires you to log in again: If you are unable to enter your password successfully, cancel the process. In the account settings, change the username in the server settings to the primary email address of the functional login.
Mobile email clients: Please check whether email retrieval continues to function correctly after the changeover. If necessary, adjust the user name in the settings to match the primary email address of the functional login.

Introduction of IOPS limits in the Enterprise Cloud March 10, 10:00 a.m. to 12:00 p.m.

Tue, 10 Mar 2026 09:00:37 +0000

On March 10, 2026, starting at 10 a.m., an IOPS limitation will be introduced in the virtualization environments of the Enterprise Cloud. The aim of this measure is to increase the stability of the overall infrastructure, ensure fair resource distribution, and avoid peak loads.

The IOPS limit describes the maximum number of read and write operations per second that a storage system can perform. The actual bandwidth depends on the block size: With a typical block size of 4 KB, an IOPS value of 3000 corresponds to approximately 12 MB/s, while with 64 KB, the same IOPS value enables a bandwidth of 192 MB/s. The standard IOPS limit in the Enterprise Cloud is 3000 IOPS per virtual hard disk. In the Research Cloud, however, these limits already exist, with the standard limit there being 1000 IOPS per virtual hard disk.

Based on our performance metrics, we have already identified VMs that regularly have increased IOPS requirements. These systems have been proactively assigned a higher IOPS limit. The respective IOPS limit can already be viewed in the Self-Service-Portal in the notes for the respective VM. If you suspect that the limit may not be sufficient for your workloads, or if you need further information, please contact the service desk (servicedesk@tu-dresden.de) at any time.

Thank you for your understanding and support in optimizing our infrastructure!

Introduction of network bandwidth limitation in all virtualization environments, 15 December 2025, 10:00 a.m.–12:00 p.m.

Mon, 15 Dec 2025 07:00:19 +0000

On December 15, 2025, starting at 10 a.m., a network bandwidth limitation will be introduced in our virtualization environments.
The aim of this measure is to increase the stability of the overall infrastructure, ensure fair resource distribution, and avoid peak loads.
The standard bandwidth limit is 2 Gbit/s per virtual network adapter. For short data transfers of up to 10 GiB, this limit can be temporarily exceeded up to 4 Gbit/s.
Based on our performance metrics, we have already identified VMs that regularly have increased network requirements. These systems have been proactively assigned a higher bandwidth limit.
The limits currently assigned to your VMs will soon be visible in the Self-Service-Portal for VM management in the Enterprise Cloud and Research Cloud.
Until this information is available, you can inquire about your assigned limit via the Service Desk (servicedesk@tu-dresden.de) if necessary - especially if you suspect performance issues.

Please refer to this overview for the buildings affected by the router restarts:

https://faq.tickets.tu-dresden.de/otrs/public.pl?Action=PublicFAQZoom;ItemID=1188

The routers are designed as a pair & only one of the two routers is put into maintenance mode & restarted at a time, so that the other continues to provide the network supply.

However, in the past we have often experienced brief interruptions when reconnecting the TRE backbone routers - please be prepared for this!

Please inform the people affected in your area of responsibility.

[Resolved] Ausfall Datennetz & Telefonie Standort MAR, 05.04.25, 10:00-14:00

Sat, 05 Apr 2025 09:00:23 +0000

Am Sa. 05.04.2025 kommt es in Folge einer Stromabschaltung zum Totalausfall der Datennetzanbindung inkl. Telefonie im gesamten Campus Marschnerstraße (MAR, DÜR, LIZ, PEZ, WIK, BA Dresden, Mensa Johannstadt, St. Benno).

Aufgrund der Stromabschaltung von ca. 08:30 - 14:00 Uhr fallen ab ca. 10:30 Uhr die beiden Backbone-Router aus, die den gesamten Standort versorgen, da die USV nur eine Haltezeit von ca. 2 Std. hat. Infolge dessen fällt die Datennetzverbindung zwischen den Gebäuden am Standort, sowie die Anbindung ans TU-Campusnetz bzw. Internet & die VoIP-Telefonie aus. Die lokale ISDN-Anlage ist zwar USV-gestützt, allerdings können wir hier aufgrund des Alters keine Garantie mehr abgeben - es ist mit einem zeitnahem Ausfall nach der Stromunterbrechung zu rechnen. Damit steht an diesem Tag in den TU-Gebäuden keine verlässliche Notruf-Telefonie zur Verfügung - bitte nutzen sie Mobilfunk oder andere externe Alternativen.

Das lokale Datennetz in den von der Stromabschaltung direkt betroffenen TU-Gebäuden wird mangels USV unmittelbar bzw. aufgrund kürzerer Haltezeiten deutlich eher ausfallen.

Das lokale Datennetz in den von der Stromabschaltung nicht direkt betroffenen TU-Gebäuden & dort ggf. lokal vorhandene Resourcen sind durchgehend verfügbar. Das WLAN wird aber zusammen mit den Routern ausfallen.

Bitte informieren Sie die Personen in Ihrem Verantwortungsbereich.
