We are approaching our forthcoming annual maintenance period, scheduled from February 5 to February 19, 2024. This maintenance is essential for enhancing our services and includes the following key upgrades:
Affected systems: Jed
Starting from Monday, 28th of August and for a period of two days, the Izar cluster will be unavailable to the users due to the migration from RHEL 7 to RHEL 8.
The downfall vulnerability, identified as CVE-2022-40982, enables a user to access and steal data from other users who share the same computer. It is found in most Intel CPUs starting from the 6th generation (Skylake) up to the 11th generation (Tiger Lake) included. For instance, a malicious app obtained from an app store could use the Downfall attack to steal sensitive information like passwords, encryption keys, and private data such as banking details, personal emails, and messages.
This morning, around 6h30, the Jed frontend was turned off due to an unexpected power issue on the direct power line. Because of this, we had to reboot the frontend, which may have caused some loss of connections.
All the running jobs as well as the ones in the queue were not affected.
We are currently investigating the cause of this problem. We apologize for the inconvenience it may have caused you.
