    3 weeks from now 2026-09-30 22:00 UTC
    Upcoming

    We are shutting down our old WiFi system (FreeScale-WiFi) on 2026-10-01. This WiFi system is currently only used in House A. All other houses are not affected by this change!

    After this date, the usage of the FeM-Net in house A is only possible via LAN or with a private router. Please keep in mind, that the usage of registered private routers (without NAT, AP mode enabled) is only allowed in accordance with the Terms of Use in houses A, N, P and houses in the Professor-Philippow-Str.

    If you have any questions, please open a ticket in our helpdesk at https://helpdesk.fem.tu-ilmenau.de/.

We are still monitoring the situation as parts of the system continue to behave strange.

Watching

The storage updates have been deployed and most of the systems seem to have stabilized. We are monitoring the situation bevor returning back to normal operations.

Identified

1 month ago 2026-07-11 11:00 UTC

We were able to pinpoint a potential issue. After the core systems maintenance last thursday no schema version upgrade to the underlying storage pool was applied, which caused I/O problems, high load and drive fragmentation. These are potentially valid causes for the current outages.

After applying the storage upgrade on parts of the core systems, partial network recovery was observed.

We are still monitoring the situation and will keep you updated. We will continue the upgrades, if the systems stabilize further.

Investigating
