2026-07-19 Pestalozzistraße 41 | Outage & Maintenance

Tim on

Some of you have been offline for four days because one of our old switches has failed. Due to the exam period and the resulting circumstances, we are unfortunately only able to replace all of the hardware with new equipment for you on Sunday evening. We no longer have any old hardware in stock for replacement and we also no longer install it.

If everything goes according to plan, we should start around 6 p.m. and be finished around 10 p.m. There is always a possibility of slight delays due to unforeseen events.

We will work through the switches one by one. Because of where the switches are located in your building, you will probably see us. Feel free to talk to us if you have any questions or are interested in what we are doing. We also welcome new members or helpers in Reutlingen, which might help things move a bit faster if something fails.

Update:

We are done, for the most part. There is stil one part of the building missing. We will be back some other day, to change our hardware out there too.

2026-07-13 Outage Heuberger-Tor-Weg

Tim on

You have been offline since around 6:13 a.m.

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

Update:

You are back online. There was a power outage which caused our hardware to be offline for around 3 hours.

10:50AM And you are offline again. We are looking into it.

2026-02-27 Complete Dormitory Network Outage (again)

Tim on

At 18:30 PM, our entire network went down (again).

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

Update:

As of approximately 19:40, 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.

We are still looking for the root cause of the same issue recurring. We are in the process of diagnosing it, but it’s proving difficult to pin down.

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!

2025-12-19 RT construction break over the holidays

Avatar photoHeinrich Griesenbach on

In recent weeks, there have unfortunately been repeated power outages as part of the ongoing construction work at Pestalozzistraße 41. According to the current status, these should come to an end with the start of the construction break from the evening of December 23 until January 7 inclusive.

On 23 December, the workers will gradually finish their work from around 4 p.m. From 5 p.m. onwards, we therefore ask you to report any noticeable problems to us immediately, so that on 24 December we still have the opportunity to replace any hardware that may have been damaged or to reach someone from the Studierendenwerk.

After 24 December, neither we nor external companies can be reached between Christmas and New Year in order to arrange short-term repairs. If a network cabinet is without power during this period, this can only be fixed after the end of the construction break.

Power is an essential requirement for your internet access. Without power, our network technology on site cannot function.

2025-12-11 Construction Work in Reutlingen

Avatar photoHeinrich Griesenbach on

We detected several outages today, including a longer one, at Pestalozzistraße 41 in our monitoring system.

While looking for the cause, we found out that there is intensive construction work going on in the building.

At the moment, all switches except one are online. The following rooms are connected to that switch:
Ground floor 8–12, 1st floor 117–121, 2nd floor 217–221, and 3rd floor 317–321.

We do not know whether these rooms are occupied during the renovation. If they are, please contact us immediately!

We will ask the Studierendenwerk what is going on.

Since all of our dormitories in Reutlingen are connected through this building, we hope that our hardware is not being damaged.

Update: A power line was cut and has now been repaired.

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. 🙂
