Triolith, Sigma down!

A problem with NSC Centre Storage means Tetralith and Sigma are not available. It appears to be the same problem that happened on Wednesday. We're still working with the storage system vendor to diagnose and fix the problem. You can expect that Tetralith and Sigma will be unavailable until at least Monday lunch. We will email all users when the systems are back online.

Please note: this is a manually updated message.

We will try to update this message when we have major user-visible problems on any of our systems. We also provide information via email to all users of affected systems (via the somesystemname-users@lists.nsc.liu.se mailing lists).

If something is not working, please don't hesitate to contact us even if this message says that everything is working! Sometimes we forget to update this page when we're busy investigating a major problem...
