On Sunday, Nov 8, an interruption of the authentication servers occurred because of a HW defect (RAID Controller).
Since the damage began insidiously and also corrupted the file system, the problem was not recognized in time and it was not automatically switched to the failover system.
Monday in the morning for safety reasons, the status of Friday night was put into operation on the replacement system.
(but without the possibility to change the password).
Since the HW defect has been fixed in the meantime, on Wednesday, Nov 11, at 8 p.m., it will be switched back to the primary system.
This will result in a short interruption (< 15 min.) in the authentication service.
Please also note that password changes made after Friday night are not taken into account.
Please excuse the inconvenience and thank you for your understanding.
