The following changes will be introduced during the maintenance interval between on 20.03.2023 (Monday) 08:30 and 24.03.2023 (Friday) 15:00.
The host key of the system will not change. You should not receive any warnings by your SSH client(s), but if there should be a warning or if you want to check that you are connecting to the correct system, you can verify the key hashes using the following list:
| Algorithm | Hash (SHA256) | Hash (MD5) |
|---|---|---|
