+Remember that bld[15-16] are reserved for courses during the day. Jobs launched while not in a lab lesson will be terminated without further notice. If you need to run jobs to prepare an exam, just add:
+  #SBATCH --exclude=bld[15-16]
+to your job script.

+<WRAP center round important>
+The server room is experiencing overtemperature due to a failed AC: many (not all) nodes are being drained and will be resumed ASAP.

+==== 2026-03-30 ====
+Possible (hopefully unlikely) service interruption due to removal of electrical bypass installed on 25/12.
+In case of emergency, the cluster will be shut down without further notice between 08.00 and 09.00 and reopened as soon as possible.
+==== 2026-03-23 ====
+Planned network interruption around 06.00. Network should remain unreachable for about 5 minutes, but the AD integration (the one that lets you authenticate against bastion-nav and ophfe*) could have issues restarting afterwards and will be checked at about 07.45.
+Active connections and file transfers will be dropped. Running jobs should continue working unless they're using remote resources.

+<del>Possible problems due to electrical maintenance. Cluster might poweroff without further warning, even if we've been reassured that won't happen (yeah... sure... hope it's not just like the last time...).
+</del> No unplanned shutdown this time

+==== 2026-01-07 ====
+  * Recovered (partially) from the emergency shutdown on XMas. /archive is currently readonly and it's possible not everything is accessible -- we're investigating the issue
 ===== 2025 =====
+==== 2025-12-25 ====
+  * Emergency shutdown: data center temperature too high (>50°C) could cause long-lasting issues
+==== 2025-12-19 ====
+  * Maintenance shutdown. The cluster will be unavailable till 2025-12-23 (if all goes well).
