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!

We are currently investigating the cause. As soon as we have more information, we will update this blog post.

Update:

As of approximately 00:15, everything should be back online. There may still be some issues, so please let us know via the contact form if you experience any problems.

2026-02-11 Hardware replacement in Franzviertel & Eugenstraße

Tim on

On Wednesday, February 11, 2026, we will be replacing the old network switches with new ones in your dormitory. This will result in temporary interruptions to your internet connection.

Schedule: We will start in the afternoon at Eugenstraße 57/1, 57/2, and 57/3, then proceed to Landkutschersweg 10, Provenceweg 7, and Provenceweg 9.

We will keep you updated on the progress and any changes via this blog post. If you have any questions or issues after this, feel free to contact us via the contact form.

UPDATE

We’ve completed everything, and it should now function normally.

2026-01-08 Maintenance Hibuka in the Franz Quaters and Eugenstraße

Malte on

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.

2025-11-30 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.

lightning strike Provenceweg 7/9

According to yesterday’s diagnosis, it seems that a lightning strike damaged some chips on the switches in the basement.

We are currently setting up the configuration on the new switches.

Afterwards, we will install the switches in Provenceweg. This will cause a brief network outage, as we will have the cables in hand.

We won’t be able to respond to emails in the basement. If you have any questions about the duration, come visit us in the basement at number 9 (towards the center of the building).

Update 12:30 PM: Everything has been swapped out and upgraded from 100 Mbit/s to Gigabit. Feel free to run our speed test and let us know if something still isn’t working.

Failure 21 Oct 2021

140 optical fibers have been separated during a bridge demolition, as a result the Französische Viertel is offline and all the dormitories that are connected over it, i.e. Eugenstraße and Hechingerstraße.

The repair starts at 0:00 am and is scheduled until 5:00 am.

If you are not back online in the morning restart your router.

We have nothing to do with the demolition of the bridge, nor with the repair of the fiber optics. Let’s hope the guys and gals who are fixing it tonight do their job well!

One night without internet is not nice, but …

Update 8:56 pm: Since half an hour the Französische Viertel is back online. Eugenstraße followed, we are waiting for the Hechingerstraße.

Update 8:29 am: Between 8 and 10 pm all dorms went online again. Thanks to our local fiber optics company TüNet!
