-New year's timeline:
+===== 2025 =====
-  * On **Jan 13, 2025** /archive will be set **read-only** to avoid potential data loss.
-  * On **Jan 15, 2025** the cluster will be **completely shut down** for about 2 weeks.
+==== 2025-10-15 ====
-Operations will be resumed ASAP.
+  * **/scratch is full**: please delete unneeded data, and archive the rest; if it does't get better in a couple of days, we'll have to run the enforcement script that deletes older data -- **IT'S NOT POSSIBLE TO RECOVERY DATA DELETED BY THE SCRIPT!** See (again) [[oph:cluster:storage#scratch|the storage page]] for more info.
-</WRAP>
+==== 2025-08-25 ====
+  * All nodes except bld17 (that was already down) should be fully operational, but it's not possible for us to check for dataset coherence: please **check your datasets/results**, expecially the ones you were working on at the time of the blackout; **double-check** (or discard and recreate) the ones you were writing to!
+==== 2025-08-22 ====
+  * Started power-on. Some disks are corrupt and require some work to be recovered.
+  * [22:42 GMT+1] Cluster is *mostly* operational, the downed nodes will be fixed in the next days
+==== 2025-08-21 ====
+  * Power line is still unreliable: deferring poweron till tomorrow morning
+==== 2025-05-09 ====
+  * slowness resolved (backup completed)
+==== 2025-05-08 ====
+  * generalized slowness: due to ongoing backup, access to /home is really slow. A concurrent check of the underlying RAID volume made it even worse. Check have been paused and backup is nearing completion, so the system should soon return to normality
+  * mtx12 is offline again due to RAM issues
+==== 2025-04-22 ====
+  * recreated missing reservations -- please check names with ''scontrol show res''
+  * mtx12 is (temporarily, we hope) down due to RAM issues
+==== 2025-04-18 ====
+  * Maintenance (nearly) completed. Two nodes are still down (gpu01 and gpu02), and some jobs migh have failed when scheduled on misbehaving nodes (bld17 and bld18, now fixed)
+  * **15:30 Update** all the nodes are currently working: don't break'em! Happy Easter!
+==== 2025-04-10 ====
+  * Created a reservation to avoid having running jobs during maintenance (**2025-04-16T10:00** to **2025-04-18T15:00**); we'll do our best to reduce downtime, so the cluster //might// come back online sooner than planned
+==== 2025-03-31 ====
+  * <del>We're experiencing issues with logins on bastion-nav from domain STUDENTI.</del> Fixed
+==== 2025-03-27 ====
+  * <del>/scratch and many nodes are currently down due to technical issues. We're working on it.</del> [9.00] Everything appears OK
+==== 2025-01-13 ====
+  * /archive is now **read-only** to avoid potential data loss during cluster move
