The Fabrikstraße dormitory runs via the Rossneckar site by default, as we have a considerably higher speed there. As a backup, however, there is also an adequate connection directly at Fabrikstraße.

The connection from Rossneckar (both Internet and the connection to Fabrikstraße) runs past the construction site of the new university campus in Esslingen. However, this connection must be rerouted. We have planned this for a long time and have procured a replacement line for the Rossneckar dormitory during the reconstruction. This also works and was therefore not affected by the cable rerouting that started today.

However, the backup line, which goes directly to Fabrikstraße, has had problems of a technical nature. As a result, the tunnel to our site in Vaihingen did not work. That is why the traffic did not automatically switch to the backup link today when the line to Rossneckar was cut. Since we need the backup line only very rarely due to a network of several switches in the Rossneckar to several switches in the Fabrickstraße, the problem was not noticed before. However, we were able to solve the problem. Since approx. 12:05 the Fabrikstraße is again supplied with Internet. As soon as the cable rerouting to Rossneckar is completed, we will then also have a functioning second connection, so that the next time there is a problem with devices in Rossneckar, Fabrickstraße should not be affected.

We are lucky. A volunteer will probably still be on site during the day today and not just in the evening, as is often the case with volunteers. We hope that he will be able to fix the problem immediately. However, since we cannot yet pinpoint the exact problem, it is difficult to make a prognosis.

No other errors have appeared. We are therefore closing the incident.

The problem seems to be solved. We will continue to observe for some time.

After initial tests, the DHCP server for assigning IP addresses and the radius server for logins seem to be functional.

We suspect that the central gateway server for our W-LAN does not create routes for new clients. This means that it is not possible for the dialled-in clients to connect from the W-LAN network created for the device in the direction of the Internet. The gateway servers are the central nodes in our network to provide a separate secured network for each client in the W-LAN.
