2026-04-12 Hardware swap | Maintenancework in Hohenheim

Tim on

In Hohenheim, we’re moving forward again: on April 12, 2026, we will replace the old hardware in three buildings, which should result in an “improvement” to the internet connection.

The affected buildings are Fruwirthstraße 11 and 13, as well as Welfenstraße 80.

  • The work will start at approximately 2:30 PM and last until about 6:00 PM.

We will work through the buildings one by one. Depending on the number of connections, the internet outage may last between 30 to 60 minutes. (For some, it may be shorter—depending on where your port is on our switches. So don’t be surprised if your neighbor gets their internet back before you do.)

2026-03-11 Planned-Maintenance | Hardware replacement Fichtenweg 5

Tim on

On Wednesday, March 11, 2026, we will replace the old switches with new ones at Fichtenweg 3. This may cause brief internet outages in the building or on individual floors.

We will start at around 3 PM in the basement and work our way up through the floors.

Feel free to approach us if you see us.

Update:

We have finished the replacement in your building.
If you have a gigabit-enabled device, you should be able to use 1 gigabit synchronously.

2026-02-07 Post-processing Total failure

Avatar photoHeinrich Griesenbach on

After yesterday’s outage, we are fixing some smaller problems.

We cannot clearly name the cause of the error yesterday. What is certain is that our batteries should buffer power outages for 30–45 minutes. Instead, they switched on and off many times per second for a very long time until they were exhausted after several hours.
Now the devices need to be replaced.

Without power, our hardware shut down at around 9 p.m., and our network went offline.

Until about 1 a.m. today, work was done on site to fix the problem, and in the end power was brought from another room into the server room.

Work started again at 9 a.m. today. We are setting everything up again and are looking for the cause of the loss of the connection to Reutlingen.

We may update this article if necessary.

Update 3 p.m.: Welcome back Reutlingen and Hechingerstraße!

TüNet is measuring a line for us, so you will be briefly offline. Start: 10:30 a.m.

Update: Finished testing and upgrade of the connection at 12:00.

Update 15.01.2026: Unfortunately, connection quality has deteriorated again since yesterday evening, resulting in packet loss. We are working on a solution.

Update 16.01.2026 13:10: We have replaced a component. The issue should now be fixed. We will address the underlying problem with the fiber provider during the week.

Update 29.01.2026: TüNet will measure the connection again tomorrow, 30.01.2026, beginning at 8:00 am. All dormitories of the French quarters as well as Eugenstraße will be affected by a short internet outage.

2025-12-21 Preventive switch upgrade in Schwerzstraße

Avatar photoHeinrich Griesenbach on

In Schwerzstraße 2, one switch has been showing unusual values in our monitoring for some time. To avoid it failing over the holidays, when we might not be able to arrange a replacement or repairs at short notice, we will carry out a preventive upgrade to our current network equipment.

We plan to leave Tübingen on Sunday at around 12:00. Accordingly, we will arrive in Hohenheim during the afternoon and start the work there.

Please expect at least two hours of work. During this time, the network will be unavailable several times for short periods. We will update this blog post as soon as the work is completed.

If anything is still open after the upgrade, we will probably be able to follow up on Monday or Tuesday. But please contact us immediately if anything does not work after the upgrade.

2025-11-30 Maintenance Upgrade Hibuka

Avatar photoHeinrich Griesenbach on

At the Hibuka in the French Quarter, we were able to recruit an Erasmus student for our working group for last week.

Many buildings in the quarter currently do not yet have gigabit connections in the rooms. We are using this opportunity to upgrade the local infrastructure.

Wankheimer Täle 1 forms the central uplink of the French Quarter as well as the buildings in Eugenstraße. During the work, there may be temporary internet outages there.

Our team will start on Sunday, 30 November 2025, at around 10 a.m. and will work its way from building to building. Anyone who would like to have a look at our network technology is warmly invited to stop by.
We will update this blog post regularly throughout the day.

Update, Saturday 6 p.m.: We will only start installation work tomorrow at 12 o’clock.

Update Sunday 1 p.m.: we are starting in Wankerheimer Täle 1

Update Sunday 5:20 p.m.: Provenceweg 1 and Landkutschersweg 4+6 are pretty much finished.

There will still be a short outage of the entire buildings when we switch the fiber connection from 1 to 10 gigabit.

Update Sunday 7 p.m.: The switch to 10 gigabit could not take place due to excessive attenuation on the fiber. The outage lasted 1.5 hours, longer than expected, because diagnostics and rollback were necessary.

Update 16.12.2025: Using new fiber patch cables, we will try to optimize the attenuation on our connection between Franz-Viertel and our server room in Fichtenweg this evening. There will be a few very short outages in Franz-Viertel and Eugenstraße.
