[Snic-users] Tetralith and Sigma down

[Mats Kronberg]

Dear Tetralith and Sigma users,

Tetralith and Sigma are unavailable since around 17:10 CET today due to
a technical problem.

Initial analysis: a problem in the fast interconnect network caused jobs
to fail (and also caused the storage system to stop working, which would
have killed even more jobs).

It's likely that all jobs that were running at 17:10 have failed.

The cause of the problem is known, and we believe the systems will be
back online within a few hours.

Check https://www.nsc.liu.se/systemstatus/ for updated information.
