Planned Maintenance – Keycloak Database Migration from 2025-10-09 20:00 CEST to 2025-10-09 22:00 CEST

This maintenance has been concluded as planned.

This maintenance is now starting as planned.

As part of our ongoing improvements to our IT infrastructure, we will
transfer the Keycloak databases to our new high‑availability Galera
cluster.

This upgrade will improve the reliability, scalability, and performance
of our authentication services.
On 09 October 2025, between 20:00 and 22:00 (CEST), SSO logins may be
temporarily unavailable for short periods.

Any interruptions will be kept as brief as possible, and all services
will be restored immediately after each migration step.
We kindly ask for your understanding and patience
during this necessary maintenance work and look forward to providing
you
with an even more stable service in the future.
