2026-02-07 Post-processing Total failure

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!

2026-02-26 Complete Dormitory Network Outage

At 9:30 PM, our entire network went down.

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.

2025-12-19 RT construction break over the holidays

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

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

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.

2025-11-2 Maintenance: Hardware Upgrade Pestalozzistraße 65

On Sunday, November 2, 2025, starting at 4:00 PM, we will replace your network hardware with new equipment. This upgrade will provide you with Gigabit synchronous connectivity directly to your room.

The hardware replacement is expected to take approximately 1.5 hours, from 4:20 PM to 5:50 PM.

Update: We finished our work. If something is not working or you, contact us!

13-10-2025 Pestalozzistraße 63

Unfortunately, a switch serving 24 rooms (rooms 101–125, pest63) has failed.

We are using this incident as an opportunity to upgrade your building to our new hardware, which will result in a brief outage for everyone living there.

However, this will not happen until tomorrow (October 14, 2025) at the earliest. As soon as we have a precise time for the hardware replacement, we will update this post.

Update 14/10/2025 7:50 am: This afternoon a quick fix will be done. In the next few days, we will upgrade to the latest MikroTik switches, so you will then have gigabit.

Update 14/10/2025 1:40 pm: Rooms are online again. Upgrade to gigabit will be probably on Sunday.

Update 21/10/2025 8:15 AM: Reboot of the building

Update 21/10/2025 22:54 PM.: Unfortunately, the quick fix broke down at around 8:00 a.m. today. In the evening, I set off to make sure that rooms 101-125 were back online. However, when I unplugged and plugged the master switch back in, it broke, which means that the whole house is now offline. Unfortunately, I won’t be able to fix it tonight, but I’ll take care of it tomorrow right after work. I’ll replace the hardware as mentioned above, and then the building should run smoothly for a good few years. So if everything goes according to plan, you’ll be back online tomorrow evening.

Update 22/10/2025, 9:41 PM.: I have replaced all switches, and the internet should be back up and running throughout Pestalozzistr. 63. While I am still making some best practice changes, there may still be brief outages. Thanks to the switch to new hardware, this dorm now has gigabit internet, which is 10 times faster—however, most of you are using old routers that can only handle 100 Mbit/s, so most of you won’t benefit from this.

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.

2024-06-10 Pestalozzistrasse 65 + 63

In the house at Pestalozzistraße 65, it looks like a device died.

The following rooms are probably affected: 222, 223, 301, 302, 303, 304, 305, 306, 307, 308, 309, 310, 311, 312, 313, 314, 315, 316, 317, 318, 319, 320, 321, 322.

If we have access to the tech cabinets and the locks haven’t been changed again, we can probably install new hardware in the evening and get you back online.

Please contact us as soon as possible if you notice any problems.

Update 3:20 pm: Now all the house is offline.

Update 4:26 pm: got an report that 63 is down.

Update 8:05 pm: last tests, but you all should be online and the number 65 upgraded to gigabit speed.
