[Berzelius-users] Berzelius downtime on Wednesday 14th of January

[Filip Polbratt]

Dear Berzelius and Berzelius-Hopper Users,

on 2026-01-14 07:00 we will start a maintenance window for several tasks 
that require significant downtime of the clusters. The primary reason 
for this downtime is electrical work which require the power to the 
computer room to be cut during the work. There will also be work done on 
the cooling loop providing cold water to the computer room.

Berzelius, Berzelius Hopper, and the shared storage are affected by this 
downtime.

We are scheduling this maintenance window to start on the 14th at 07:00 
and to last to 14:00.

We might be able to return the login nodes and some compute nodes to 
service earlier. However, this should not be expected and depended upon.

=== Additional topics ===
To better understand the users’ needs and to plan our upcoming training 
activities, we invite all Berzelius users to share their input through a 
short survey. Please take a moment to fill out the form here:

Thank you for helping us improve the Berzelius user experience.

Best regards,
Filip Polbratt
