In calendar week 38 our electricity supplier has to conduct the 5 year maintenance on the transformer station supplying the modular data center, which hosts our system Emmy. This maintenance requires shutting down the power supply of the data center requiring a full shutdown of all systems at this site. As the central Slurm controller and the storage for Home and Software are installed on this site, Grete will also have a downtime.
Due to unforeseen technical problems at several places (building power supply, fire-extinguishing system and user database synchronization) we have to extend the downtime of Emmy and Grete until Sept 22nd 12:00.
