Bulletin 21.10.2026

Bulletin updated October 22, 9.20: All services are functioning normally again.

Moodle, Studies Service and several other university web services were unavailable from the afternoon of Wednesday, October 21.

The outages were caused by a security vulnerability discovered yesterday in PHP software used to run web services. To protect our users' data, we had to temporarily shut down several of our online services.

Moodle, Studies Service and other online services are now operating normally again. If the outage affects teaching schedules or examinations, your course teacher will provide further information.

We apologize for the inconvenience and uncertainty caused by this unexpected disruption!

More information: broader bulletin in Flamma.
