Outages in dormitories with new hardware platform

Gret-Palucca-Str. 9 Güntzstraße Marschnerstraße Reichenbachstraße Gutzkowstraße

Written by Marcel Beyer, 2020-01-14.

Recently, there have been repeated outages in the dormitories Gret-Palucca-Str. 9, Güntzstrasse, Marschnerstrasse, Reichenbachstrasse, Gutzkowstrasse. We would like to apologize for any inconvenience this may have caused. Unfortunately we can not guarantee that these were the last failures. The situation with the relatively frequent breakdowns in these dormitories does not fulfill our own demands. We are working accordingly to determine the causes, to be able to prevent these failures in the future.

We are already operating our new hardware platform in these dormitories, which enables us e.g. to provide WiFi aside of the wired connection. We have been operating this hardware in the first dormitories since October 2019, so we have not yet been able to gain as much experience with the hardware as with the old hardware, which we have been using for over 10 years now.

At Güntzstraße we also have to use old multimode fiber optic cables, which have very high attenuation. These are also currently causing problems. The Studentenwerk has already started to replace these cables with new singlemode cables. So that there should be initial improvements after the fibres are replaced.

To be able to solve the initial troubles with our new platform, we are dependent on having a lot of information about the failures. We are currently in the process of developing a system with which we can automatically detect issues in the dormitories and collect some information about the outages.

Until then - and also for the past failures - you can help us by providing information about the outages. This information could be, for example, the following:

• What dormitory and what room do you live in?
• When did the outage begin?
• Was it a total failure or just a very slow connection?
• In Gret-Palucca-Straße: Was only the cable connection affected or also the WiFi provided by us?
• Did the Internet break down abruptly or did it deteriorate gradually?

If you are technically more experienced:

• Are the following addresses pingable during the outage:
• Can you still resolve addresses via our DNS server?

You can send us this information by e-mail to

On our status page you can also check at any time whether a failure is already known to us.

Thank you very much for your help!
