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!

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.

2025-12-07 Outage Eugenstr.

Jonas on

Our monitoring solutions indicate that it can no longer reach our switches in Eugenstr. The reason for this is not entirely clear; it could be due to a switch that has died of old age or to some kind of problem with the uplink.

We will take care of it today.

Update: Eugenstr. is back online – if problems are still appearant, please contact us.

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.

2025-10-15 Partial Outage in Fichtenweg 1

Jonas on

Around 12:10, one of the two switches at Fichtenweg 1 failed, causing most of the rooms to currently have no internet connection.

 

We are on our way to replace the switch.

Update: since 1:27 pm the house is online again. The priority to upgrade this house has been increased.

Small Recycling Project – September 2025

Some of you are kind enough to leave your router behind when you move out, so other students in the dorm can use it. Of course, these are not always the newest devices – sometimes we even find very old ones.

To keep things organised, we started collecting the leftover routers together with the caretakers here in Tübingen at Fichtenweg. By now, about 25 devices have been gathered. Anything that does not support modern Wi-Fi or current encryption standards is sorted out.

The working devices are passed on – together with a matching network cable – to the “WHO Dorfrat”  (student dormitory council). They distribute them to people who only need simple internet access and for whom an older router is still good enough.

What matters to us is that you have really good and stable internet in the dorm. The internet connection in your room almost never fails – if you have problems, it is usually the router or its settings. Just contact us and we’ll show you how to set up your router correctly. You should basically have nearly 100% availability.

A big thank-you goes to the caretakers, who have been very active in collecting the routers!
