Seit gestern Abend gibt es vereinzelt Störungen. Grund dafür ist ein Strom-Ausfall am Internetknotenpunkt DE-CIX in Frankfurt am Main, das Problem betrifft also nicht nur uns, sondern auch andere Netze.

Laut dem Twitter-Account des DE-CIX soll das Problem in 1-2h (also etwa 2.30 Uhr) behoben sein.

On the 8th of April from 12am to 8pm the performance of network and server resources might degrade.

Reason is the load test of some components, needed for future WiFi deployment.

We're going to perform maintenance work in our dormitory Hochschulstraße on the 5th of March 2018 between 7:30 and 11:30 pm. During this period connectivity issues and outages are to be expected. We try to keep them as short as possible.

New service - HTTP Cache for Steam

All student houses except Gerok- and Hochschulstraße
Written by Friedrich Zahn, 2018-03-03. Permalink 

We are happy to announce a new service for our members, an HTTP cache. Once you enable the service in your usersuite, downloads from the supported services (currently only Steam) are redirected to an internal server, which is caching all downloaded data. Therefore multiple downloads of the same data only need to be fetched from the internet once.

The aim of this service is to reduce bandwidth usage on our uplink to the university, and to provide an improved experience, since our local network is much more capable.

We tested the service extensively, but please be aware that it will never move beyond a beta status, due to the inherent dependencies on the cached services. If you experince problems, we can only provide limited help, and you might have to disable it again.

More technical information, a list of the supported services and know problems can be found here.

Mitgliedsbeitragsänderung

Alle Mitglieder
Written by Sebastian Geisler, Friedrich Zahn, 2018-02-07. Permalink 

Beginnend ab dem 1. April 2018 erhöht sich unser Mitgliedsbeitrag von 3,50€ pro Monat auf 5,00€ pro Monat. Die Erhöhung wurde auf der letzten Vollversammlung diskutiert und beschlossen, zu welcher das Protokoll hier einsehbar ist. Die hauptsächlichen Gründe für die Erhöhung ist unser Bestreben zukünftig Infrastruktur-WLAN in allen Wohnheimen zur Verfügung zu stellen, infolge von Inflation gestiegene Betriebskosten sowie anstehende Erneuerungen alter Technik.

Um Probleme zu vermeiden, passe bitte rechtzeitig eventuelle Daueraufträge an und überweise die Differenzbeträge für im Voraus bezahlte Monate. Du kannst deinen aktuellen Kontostand in der Usersuite einsehen.

Ergänzung 2018-03-10: In der 3. Folge des MultiCast haben wir u.a. die Gründe für die Erhöhung auch noch einmal besprochen.

Heute ab ca. 19:30 werden wir defekte Hardware in der Hochschulstraße 46 austauschen. Im Zuge dessen wird es zu Unterbrechungen der Verbindungen kommen, wir bemühen uns natürlich wie immer, diese so kurz wie möglich zu halten.

Updates and Outages

Gret-Palucca-Straße Neuberinstraße Hochschulstraße
Written by Gerrit, 2018-01-14. Permalink 

Due to the recent security issuese named "Meltdown" and "Spectre" we had to install last week multiple Updates to fix our systems. While updating we ran into a few issues wich lead to a few small network outages.

On Monday a service didn't restored properly after a system restart so the connectivity at Hochschulstraße was limited to those who connected their computer or router prior to the reboot.

In the evening a unexpected reboot of one of our servers in a critical moment lead to outage of Gret-Palucca-Straße and Neuberinstraße due to a routing issue.

Please excuse the inconvenience.
