Recently resolved problems and planned maintenance
- 2020-06-25 00:00 - 09:30: Too-low quotas accidentally set on some project directories, causing some jobs on Tetralith to fail
- 2020-06-04 08:30 - 13:00: Bi and Accumulus filesystems unavailable due to a unplanned power outage in our computer room Kärnhuset. All running jobs failed.
- 2020-06-04 08:30 - 12:00: Tetralith and Sigma unavailable due to a unplanned power outage in our computer room Kärnhuset. All running jobs failed.
- 2020-05-15 19:13 - 22:25: One of the Tetralith login nodes (tetralith2) crashed, probably due to a hardware problem.
- 2020-05-13 18:45 - 2020-05-14 19:00: Logins to Bi blocked for addresses outside of SMHI due to the same concern as below.
- 2020-05-13 18:45 - 2020-05-14 12:10: Logins to Tetralith and Sigma disabled. We received reports of multiple HPC centres abroad being subject to intrusions. The information about what security vulnerabilities may have been used is scarce, so we took the decision to turn off new logins to Tetralith and Sigma while we tried to get more information and prepared to apply the latest security updates.
