[Berzelius-users] Berzelius downtime calendar week 4, 20th to 24th of January

[Filip Polbratt]

Dear Berzelius Users,

The connections between the storage servers and the client nodes (DGXs 
and login nodes) has been unreliable when stressed.

Berzelius will be offline for maintenance until this is fixed.

You can view system status for systems at NSC on this page:

Best regards,
Berzelius staff
