*'''25 Feb. 2021 - Next major maintenance window on 08 March 2021:''' Please have a look at the [https://wiki.alice.universiteitleiden.nl/index.php?title=News#Maintenance maintenance page] for details on our planned work and how it affects you.
+
*'''17 Aug 2022 - REMINDER - ALICE system maintenance on 22 Aug 2022:''' We will perform system maintenance on ALICE on 22 Aug 2022 between 09:00 and 18:00 CEST. Our primary focus will be the high-availability set up of ALICE in addition to other maintenance tasks. This will require us to take all compute and login nodes of the cluster offline. It will not be possible to run any jobs and access data on ALICE. The login nodes will be rebooted and all active terminal or X2Go sessions will be terminated. Until maintenance starts, you can continue to use ALICE as usual and submit jobs. Slurm will also continue to run your job if the requested running time will allow it to finish before the maintenance starts. If you have any questions, please contact the ALICE Helpdesk.
*'''12 Feb. 2021 (Update 22 Feb. 2021) - SSH Connection Stability:''' If you recently started experiencing that your ssh connection is breaking up after a few minutes of being idle, please check the settings below for you ssh configuration for ALICE. If this does not solve the issue, please contact the ALICE Helpdesk.

*'''01 Aug 2022 - ALICE system maintenance on 22 Aug 2022 - First announcement:''' We will perform system maintenance on ALICE on 22 Aug 2022 between 09:00 and 18:00 CEST. Our primary focus will be the high-availability set up of ALICE in addition to other maintenance tasks. This will require us to take all compute and login nodes of the cluster offline.

*'''01 Jun 2022 - Disabled access to old scratch storage:''' As previously announced, we have disabled access to the old scratch storage. '''We will keep the data available until 30 June 2022'''. Afterwards, we will start to delete data so that we can repurpose the storage within ALICE. You can request temporary access by contacting the ALICE Helpdesk. See also the wiki page: [[Data storage|Data Storage]].
** MobaXterm: Go to Settings -> SSH -> SSH settings and enable "SSH keepalive"
 
**PuTTY: Go to Settings -> Connection -> Set a non-0 value in "Settings between keepalives" (e.g., 60)
 
*'''25 Jan. 2021 - Outlook for ALICE in 2021:''' We have updated the section outlining our expansions plans for ALICE in 2021 ([[About_ALICE#Future_plans|Future plans]]). Two major items this year will be the addition of a new parallel file storage system and the expansion of the GPU nodes. But there is more on our agenda, so stay tuned...
 
*'''08 Jan. 2021 - SURF HPC Workshops:''' SURF is offering HPC-related workshops on various topics. You can find a list of upcoming workshops (and more) on the SURF website ([https://www.surf.nl/agenda/onderzoek-en-ict Link]). Workshops of interest to HPC users are:
 
**Webinar Introduction Supercomputing
 
**Webinar Introduction HPC Cloud
 
**Using the Amsterdam Modeling Suite in HPC systems
