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.

Members’ meeting 2025 on January 6, 2026

Avatar photoHeinrich Griesenbach on

The general members’ meeting for the 2025 association year will take place on January 6, 2026.

Originally, a date in December was planned, but unfortunately there was not enough time at the end of the year.

A regular general members’ meeting is required by association law. Certain deadlines and formal requirements must be met, regardless of how full the calendar is at the end of the year. For this reason, the meeting will now be held at the beginning of January.

To avoid this situation in the future, we will probably move the general members’ meeting to the summer.

2025: an important year

2025 is a special year for the association.

It is the first year in which we have concluded the contract with the Studierendenwerk for operating the network. This means that a long-open issue has now also been formally clarified and placed on a stable basis.

Growth of the association

I am also pleased that I was able to invite 18 people to this year’s general members’ meeting.

Since the founding of the association, the number of members has therefore doubled.

It is increasingly noticeable that structure and activity in the association are slowly gaining momentum. Tasks are being distributed better, processes are becoming clearer, and engagement is growing steadily.

2025-12 What actually happens when you write to us?

Avatar photoHeinrich Griesenbach on

Since April, our support has been using a new ticket system: FreeScout.
Before that, things were often confusing, with only one inbox that was read and answered by several people. Now we have a better overview. And we have some numbers that we find quite interesting and would like to share with you.

Numbers since the start

193 people have written to us.
We have sent 610 replies.
That is about four per day.
We have now closed 216 tickets or cases.
For 81 of them, one reply was enough.

The biggest rush, as always, comes during move-in to the dormitory. There are many new people, and accordingly many questions.

How fast we reply

Short answer: usually quite fast.
About half of all requests are answered within one hour.
On average, it takes 48 minutes.

We do this on a voluntary basis. Without an office, without fixed hours. When there is a lot going on, like during move-in, we pay especially close attention so that no one has to wait too long for a reply.


When is a ticket finished?

This does not happen automatically for us.
When we reply and then do not hear back from you, we leave the ticket open for the time being. Maybe our answer helped. Maybe you need more time. Maybe the email got lost. We do not know.

At some point, when there is time, we go through the open tickets and close those where nothing more is happening.

That is why it looks like many tickets are only solved after more than two days. In reality, most of them are finished much earlier. We just do not press “closed” immediately.

How much back and forth is needed?

In three out of four cases, one or two replies are enough. Sometimes it takes a few more messages, or there is simply another “Thank you” and a “Have fun on the network” at the end. That makes the statistics longer, even though the topic was actually already finished.

Move-in phase and routers

The data clearly shows the move-in phase. And that many of you only start dealing with the topic of internet in the dormitory and routers after moving in.

Many then seem to go, under stress, to the nearest shop that sells routers and let themselves be sold whatever the shop wants to get rid of at the moment.

The problem:
These “specialist salespeople” unfortunately do not inform themselves at all about what our five and a half thousand users actually need.

It is really a shame when some of you ruin probably the best internet connection you have had so far, and will probably have in the next five to ten years, with a bad router.

In local retail, a router probably costs 30 percent more than online. That is completely fine.
But please do not buy anything that is already marked as insufficient on our website.

We really put a lot of effort into our guides. And if you are not sure about a device that is not on the list, just ask. We are happy to help you.

If you have questions, get in touch!

We usually reply quickly and do our best.
By now, we even know quite precisely how fast we reply.

2025-12-07 Partwise outage of Pestalozzistr. 63

Jonas on

Due to an oversight on my part, I have unfortunately taken Pestalozzistr. 63 partially offline. I apologize for this. I will take care of getting you back online today.

Update: Pestalozzistr. is back online.

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.

2025-11-15 Exchange of Switches in Fruwirthstr. 3, 7 & 9

Jonas on

Hello everyone,

During the course of the evening, we will be replacing switches at Fruwirthstr. 3, 7, and 9, which will cause the internet to be down for approximately one hour at each location.

We will let you know as soon as we are done – everything should be working again by tomorrow morning at the latest!

Update 9:42 p.m.: Fruwirthstr. 3 has already been completed—if you encounter any problems, please report them as soon as possible!

Update 00:28: Fruwirthstr. 7&9 have also been swapped—and we’re back in Tübingen.

So you should all have internet again – and new switches that will last a long time. 🙂

2025-10-09 Reutlingen Pestalozzistr. 67

A switch that is serving 24 rooms died today.

Instead of replacing the switch we will upgrade the house to gigabit.

We will be there tonight.

Update

9:30 PM – We are done and everything should be working normally again. If there are any issues still, let us know via the contact form.

Gigabit? Well… (Update from September 15, 2025)

Avatar photoHeinrich Griesenbach on

Almost two years ago I posted some numbers about how many people in our student housing actually use gigabit-capable devices. Today I checked again – and honestly, it’s not the big breakthrough yet:

Location Dec 2023 Sep 2025 Change
Geislingen 25 % 35 % +10
Albstadt 53 % 48 % −5
Sigmaringen 33 % 26 % −7

Geislingen improved a lot, Albstadt dropped a little but is still on top, and Sigmaringen is now down to only 26 %. Hard to say if this is a real trend – the measurement happened during semester break, so the sample is smaller. But still, the direction is interesting.

Router returns: a sad story

We are also collecting routers that students left behind when moving out. The result? Not great: less than 5 % of these devices can even do 5 GHz Wi-Fi – and so they can’t handle gigabit properly.

Of course, if someone owns a good router, they don’t leave it behind. But still, it’s shocking how many people were using outdated hardware: old Fast Ethernet ports, no 5 GHz, weak Wi-Fi chips. No wonder the speeds suffer.

Conclusion

For us that means: more awareness needed! Either many students don’t know what their connection could really do – or maybe they just don’t need much internet at all. Apart from one building in Tübingen (we’re still waiting for the key), we’ve already put up our own posters in all 102 student housing buildings. Let’s see if that helps.

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!
