Dear Tetralith users,

On Tuesday next week (February 7th), we will update and reboot the
Tetralith login nodes.

We will keep downtime to a minimum, but the work may take anywhere up to
2 hours per login node.

Login node tetralith2 will be rebooted starting 09:00 CET.

Login node tetralith1 will be rebooted starting 15:00 CET.

Logged-in users will be logged out. Running and queued batch jobs will
not be affected.  Running interactive sessions will be terminated.

While one login node is rebooted, the other will be available, and new
SSH and ThinLinc sessions will be sent to the working login node.
