+===== March 23, 2023: planned maintenance/upgrade =====
+I am planning to upgrade the HPC's backend storage systems to a new version of their operating system (CentOS)¹ on Monday, March 27rd at 9AM (EAT). Due to the invasive nature of these upgrades I will need to stop existing SLURM jobs and restrict access to the clsuter. The work will probably take the entire morning.

+¹ Technically speaking, we are upgrading from CentOS 7 to CentOS Stream 8, which is the same upgrade I've performed on several compute nodes over the past few months. This is a major upgrade that we only perform every five years or so, and will modernize and increase security on HPC.
