Subject: [Sigma-users] Reboot of the Sigma login node
Message-ID: <877bss6g1i.fsf@nsc.liu.se>

Dear Sigma users,

On Friday morning (February 6th) from 07:00 CET we will upgrade and
reboot the Sigma login node to apply security updates.

While this is going on, you will not be able to access Sigma.

The work will take approximately 30 minutes.

Running and queued batch jobs are not affected. Running interactive
sessions will be terminated when the login node reboots.
