Municipal Services Are Available Again
The services of the state capital of Mainz, which were limited on Monday, have been available as usual again since Tuesday, September 29, 2026. The affected digital services are also accessible again.
The incident was triggered by a security alert—classified as highly critical—regarding an IT product used in municipal data centers. As a precautionary measure to protect data, access to the affected applications was temporarily suspended. The systems were checked and then gradually made accessible again. Based on the checks conducted so far, there is no evidence of an attack or a data breach.
Residents whose appointments were canceled on Monday can schedule a new appointment through the online appointment booking system. The city administration thanks you for your understanding.
