On March 21, 2025, we will finally install our new MikroTik Cloud Core Router – CCR2216.
All important devices in our network have names. Our new core switch from MikroTik is called “Corey McRotik.”
As the central core switch, it connects all our network segments.
Many people don’t realize that we run a real, independent network.
All student dormitories in Geislingen an der Steige, Hohenheim, Nürtingen, Reutlingen, Albstadt, and Sigmaringen are connected to us in Tübingen and meet here at Fichtenweg 5.
(This is also why we cannot simply add dormitories that are connected via DSL, like those in Rottenburg, to our network.)
During the upgrade, all dormitories will go offline one or multiple times for a short period, depending on how we need to switch the fiber optic connections.
We chose Friday during the semester break to minimize disruptions for students and avoid interfering with the Studierendenwerk.
Our homepage is no longer hosted on a server at Fichtenweg—it is now hosted externally.
The main reason for this change was a series of power outages in our server room, which not only took all dormitories offline but also made our homepage unavailable.
We don’t expect frequent power outages, but with this change, we can provide more reliable updates in case of problems.
In short:
No need to worry, no emails, and please do not report the planned outage on Friday at 6:00 PM—we are aware of it.
We will be in the server room, literally holding cables in our hands.
We will update this message once we are finished.
If you still have problems after restarting at least one router, please contact us immediately via the contact form.
We will stay on-site for a few more hours to fix configuration issues or, if necessary, undo changes to keep the internet downtime as short as possible.
If you are interested in large networks, feel free to contact us (contact form: Mitmachen).
No prior knowledge is needed!
This year, we will replace switches in over 100 buildings—it’s manual work, so every helping hand is welcome.
If technology is not your strength, but you still want to help, we would really appreciate it.
As you can see from this not-so-perfect text, we could also use someone who can write better texts, design announcements, or simply organize tasks.
Right now, we are mainly active in Tübingen, but we already have one person in Hohenheim who recently joined to help on-site.
We really appreciate people outside of Tübingen because you can reach locations faster.
For example, you could help someone in a dorm with router issues, check if a construction crew accidentally cut a fiber optic cable, or look in the basement to see if a power outage is causing a network problem. All of this is much more difficult for our volunteer team in Netz-AK to handle from Tübingen.
6:16 pm update: after 4 minutes of downtime we finished. If anything is different for you, contact us!
Imagine you’re living in a student dorm that has had fiber optic since 1974. And then, in 2024, you suddenly get an advertisement for the “soon arrival of fiber optic” in your mailbox.
