The QRIScloud Tier2 NFS service has been offline since Friday evening. This is affecting access to Tier2 collections (via both Standard Access and NFS-only Access) and has also caused the ssh services machines ("data", "ssh1" and "ssh2") to stop working. Other systems may also be affected.
We are investigating the cause of the problem.
UPDATE - 10:20 - The primary NFS server had an extremely high load average and was not handling requests. A manual fail-over was performed, and NFS is working again. We are investigating the root cause.
