On Thursday, 26/06/2025, maintenance work will be carried out on the central email service (mail.desy.de) from 8:00 to 21:00.

During this period, there will be two shorter interruptions of the email service in the morning, each lasting about 20 minutes. In the afternoon, starting at 16:00, the email service will also be unavailable for a period of one to four hours, and email traffic will be halted.

Incoming emails will be temporarily stored and delivered to the email accounts after the maintenance work is completed.

This short-term maintenance is necessary to ensure operational safety.
