Recently resolved problems and planned maintenance

  • 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.
  • 2020-03-11 09:00 - 2020-03-12 22:30: Planned Bi and Accumulus downtime
  • 2020-03-01 10:00 - 11:30 CET: Nebula and Stratus unavailable due to electrical work on Campus.
