We have time right now and are taking the opportunity to upgrade Fichtenweg 26 with new hardware.
During the installation, you will be offline (about 90 minutes).
We will start at 9:20 PM.
Upgrade Fichtenweg 26
on Category: Maintenance Work
on Heads-Up: Friday, 06/12/2024 – New switch, new luck! 🚀
on 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.
2024-06-17 Fichtenweg 9
on We got some outages reported and decided to exchange our hardware in your basement.
You will be offline for about one hour and have a gigabit connection afterwards.
Maintenance work announcement Viktor-Renner-Straße
on On Thursday, April 18, starting around 6:30 PM, we will finally be able to equip our dormitories in Viktor-Renner-Straße with more modern technology.
For the residents, this means they will be able to use gigabit internet in their rooms afterwards.
For us as Netz-AK the upgrade also brings us major advantages in the management of our network. The switches that were previously installed in Viktor-Renner-Straße are the very last to not support various standard features and needed to be configured very differently from the rest of our infrastructure, hindering any automation efforts.
We expect the installation to take about 3 hours, meaning you will probably have unrestricted internet access again from 9:30 PM.
Update 2024-04-23: After we were initially only able to replace the switches at Viktor-Renner-Straße 2 last Thursday, we have completed all maintenance work at 4 today. If you still have problems with your internet, please contact us individually using our contact form! This is the only way we can identify the individual problems and help you effectively, because the sources of error can be very different.
As everywhere else in our network, the maximum number of IP addresses assigned in Viktor-Renner-Straße is now basically limited to 1 per connection. However, you don’t have to buy a new router now if, for example, you have previously operated a WiFi repeater and therefore need several IP addresses. For all such connections that we could identify, we have temporarily relaxed this restriction. Let us know if we missed one.
Maintenance Work Announcement week 3
on In week 3, which is from January 15 to January 21, some maintenance work is scheduled.
Hohenheim
The maintenance work starting on Friday will be long and unpleasant for the people in Hohenheim.
The fiber optic lines in Hohenheim to get extended to be used in a different location because of the renovations.
Without the fiber optic line, there will be no internet there.
The work will be carried out by a specialist company and is scheduled to start on Friday morning, which is January 19.
The work will take a long time, so we announce a complete internet outage in all student dormitories in Hohenheim from Friday morning to Saturday noon.
If it’s done faster, please avoid sending us messages all day. It won’t speed things up.
The company will complete their work as quickly as possible, and we will reconnect the fiber optics.
Tuebingen, Konrad-Adenauer-Strasse
On Thursday, January 18, starting around 5:30 PM, we will finally be able to equip our dormitories in Konrad-Adenauer-Strasse with modern technology.
For the residents, this means they will be able to use gigabit internet in their rooms afterwards.
Since we haven’t been able to implement the exclusive use of routers in Konrad-Adenauer-Strasse due to technical reasons, we will not enforce this immediately but only from the start of the summer semester (April 1, 2024).
We expect the installation to take about 3 hours, meaning you will probably have unrestricted internet access again from 9:00 PM.
Tuebingen, Schimpf-WG
There will be a maximum half-hour interruption in internet access at the Schimpf-WG. We had announced this work several times before but could never implement it due to problems accessing our hardware in the neighboring building. We cannot say exactly when this will be, but it will happen some evening between Monday and Thursday.
Network restructuring on the weekend of November 25th and 26th, 2023.
on Next Saturday and Sunday, we finally have the long-awaited network restructuring happening.
These changes are necessary to improve the performance and reliability of our network.
To minimise the impact on you, we’ve planned to carry out the restructuring early in the day. During these times, there are usually fewer users online, which should reduce any inconvenience.
The scheduled offline periods will each last about an hour. We understand that this may be a bit inconvenient temporarily, but we are confident that the long-term benefits will outweigh any short-term inconveniences.
We appreciate your understanding in advance.
Update Nov 25th 2023 4:15 PM:
Yesterday, Malte worked until 11:30 PM, and Lucas until 1:00 AM, preparing and configuring.
The implementation of network changes started this morning at 10:00 AM and resulted in a longer network interruption across the entire network (student housing and dormitories) at 10:30 AM.
The interruption lasted from 11:30 AM to 2:00 PM and then from 2:30 PM to 3:30 PM. The work was completed by 3:30 PM, and the last device came back online at 4:00 PM.
During the cleanup following the work, no further outages are expected.
Whether work will be needed again on Sunday depends on whether disruptions are reported to us or if we discover issues that are not functioning as desired.
Schimpf-Eck (Am Lustnauer Tor 1) July2023
on Surprisingly, construction work for Schimpf started last week. Each room, as usual in our dormitories, will have its own network connection with a double network socket, and one connection will be active.
We don’t consider a comprehensive alternative like WLAN networking, which is often desired, to be practical here. Those who have dealt with connecting hundreds of devices to Eduroam will understand why we are avoiding it.
In each room, you can set up your own secure and easy-to-configure WLAN with a simple router for around €35, allowing you to connect everything from a printer to a PlayStation.
The connection of the WG units in Schimpf Eck depends on the work at Pfleghof, whose starting date is still unknown to us. As surprises are possible, we prefer not to estimate when it will be ready. Getting new DSL contracts doesn’t seem sensible to us. We hope that the WG units will find a fair solution to redistribute the internet access costs or find a way to get rid of these contracts once the dormitory is stably connected to our network.
The final connection via fiber optic to our network is planned but not yet confirmed.
Hohenheim Uplink Upgrade 11:30 am till 4 pm
on Good morning dear Hohenheim residents!
Today, the Uplink upgrade will be fully implemented. If everything goes well, you will be running on 10G afterwards, and the outages will come to an end.
To transport the Uplink technology from the temporary location at Schwerzstraße 2 to the new location at Egilolfstraße 57, we will need some time. Unfortunately, during this time, the Hohenheim dormitories will be offline.
Since we have to unplug the device and then reconnect it in a different building, it cannot be avoided. However, we will hurry as much as possible.
Hohenheim 26 of May Upgrade
on It’s time!
Last night, we were given the task to carry out the upgrade.
As mentioned before, we had already prepared a new location for the uplink, which will enable all Hohenheim residences to go online.
To transport the uplink technology from the temporary location at Schwerzstraße 2 to the new location at Egilolfstraße 57, we will need some time. During this time, the residences in Hohenheim will unfortunately be offline.
Since we need to disconnect the device and then reconnect it in a different building, it cannot be avoided. However, we will do our best to expedite the process.
The estimated duration will probably be around one to two hours this afternoon, with several short outages as we make the necessary adjustments throughout the day, starting in the morning.
We will update this post once we have more information.
Hohenheim 16th of May
on We were able to accomplish almost everything we had planned yesterday.
We dismantled and disconnected the three generations of network technology that were stacked on top of each other.
We managed to clean the room to some extent with a broom we found. Once we speak to the janitor, we will find a place for all the electronic waste (see picture).
One of the switches currently in use didn’t look promising during the removal, so we will replace it this Tuesday evening (starting from 6 PM, depending on traffic).
This means that we will need to unplug the cables of the residents of Egilolfstraße 51 to 59 again, and they won’t have internet during this time. Some rooms will be offline for about an hour, while others will experience shorter outages.
Afterward, the room should be prepared for the installation of the main network connection for the entire Hohenheim area.
The relocation and upgrade of this connection still depend on the IT department of the student services.
We hope that with this cleanup operation, we have eliminated any obstacles that could potentially further delay the final resolution of the network issues in Hohenheim.
