Christmas 2024

Avatar photoHeinrich Griesenbach on

The Christmas season – for many, a time of reflection and peace. But for us at Netz-AK, it stays busy! Even during the festive season, we’re here for you. Whether it’s sudden technical issues or those little things you’ve always wanted to configure properly – we’ve got your back!

Of course, there are limits: if solving a problem requires “paid staff,” many of them are rightly on holiday now.

Why? It’s simple: volunteers rock!

A big thank you to everyone who helps us keep going. A special shout-out to the caretakers, Carmen Braun and Mrs. Hein.

Wishing you a Merry Christmas and a great start to the new year!

Your Netz-AK Team

Heads-Up: Friday, 06/12/2024 – New switch, new luck! 🚀

Hi everyone,

It’s time! On Friday, December 6, 2024, we’re finally installing the new generation of switches in the dorms on Konrad-Adenauer-Strssße. 🎉

What does this mean for you?
During the installation – about 3 hours – the dorms will be completely offline. No connection, no internet, no streaming, sorry! 🙈

Please don’t contact us during this time or ask how much longer it will take. It’ll take as long as it takes – but we promise to work as fast as we can! 💪

What’s new?
The new MikroTik switches are a test to see if they can replace our old Alcatel devices. Small tests went smoothly, but now it’s time for the real thing. Fingers crossed that everything works as planned! 🤞

Thanks for your patience and understanding – after the update, you’ll be the first to enjoy the new speed! 🖥️⚡

Your volunteers of the Netz-AK 🌐

Update: Saturday, 3:05 am we are back in Fichtenweg and configuring the last minor things. (That were very long three hours 😃 )

Update: Sunday, ~9 pm. we are replacing some modules and hope to connect the dormitories in Konrad-Adenauer-Strasse at 10 Gigabit to Fichtenweg 5.

Netz-AK goes to Hohenheim!

On Friday, the working group, along with its new members, will visit our technology in the dorms in Hohenheim. We expect to arrive at Egilofstraße around 5 PM and from there, we will visit Welfenstraße and Schwerzstraße. Whether a short tour of the campus or a visit to our dorms at Chausseefeld is possible will be decided spontaneously.

If you would like to meet us, keep an eye out for a group of nerds – it’s safer to let us know in advance using the contact form (Join Us).

The reason for the tour is our new members from Tübingen and our first interested person from Hohenheim! Besides getting to know the locations, we hope to gain insights into the needs of the dorms, which we often view as “outlying areas.”

Another move-in wave is over, and it’s time to share some statistics so the blog isn’t just about network outages.

All emails were answered by hand, and as quickly as possible.

2024-09-30 Total outage the 2nd

Avatar photoHeinrich Griesenbach on

Today (~4:19 pm), there was second unexpected power outage caused by a tripped circuit breaker (FI switch), which disconnected our systems from the network for about 90 minutes.

Since manual intervention was needed, we had a downtime of around 30 to 45 minutes before the systems were fully up again.

The outage wasn’t caused by anything we were doing, so it came as a surprise. Unfortunately, the UPS (uninterruptible power supply) didn’t last long enough until I could bike up the hill to Fichtenweg 5 to fix it on-site.

These kinds of incidents can happen, but most of you probably didn’t even notice the outage.

2024-09-11 Kaiser-Wilhelm-Strasse 10

Our systems have been showing an outage at our connections at Kaiser-Wilhelm-Strasse 10 in Geislingen an der Steige since Wednesday, September 11th.

We received the first report from a resident on September 12, 2024, at 11:42 AM.

Without such a report, we cannot take action because there can be many reasons for the outage of our connections, like construction work in the building or on the street, or other reasons for a power cut.

In the past, we have gone to sites unnecessarily with fully configured replacement devices, so we no longer respond without a report from a resident.

Since we cannot access the building and the technical rooms in the basement without the help of a janitor, no repairs have been possible yet.

We will try again today to fix the issue.

Update 10 AM: The janitor was reached and turned the power off and on again. Everything is back online. The availability and accessibility of janitors is very important!
A big thank you to the janitor for his help – he saved us over two hours of driving time.

SNT 2024

From August 29 to September 1, 2024, SNT 2024 took place in Chemnitz. Unfortunately, the Netz-AK was represented by only one person, but they were able to bring back new ideas for our work. Networks from all over Europe participated, including AG DSN, Selfnet, StuStaNet, and many others.

A big thank you to the organizers from Chemnitzer StudentenNetz (CSN) for this successful event!

Muenzgasse 7 has been shown as offline since last night.

So far, no one has contacted us. We are preparing to upgrade the building to Gigabit. (12:00)

3 PM: No power, no internet. We upgraded the hardware. As soon as the power is back on you got gigabit internet.
