The IEM website was degraded from about 3 AM till 8 AM this morning due to an ugly cascading failure. The current theory is that a Red Hat Enterprise Linux 7 bug caused a NFS client with failed memory DIMM to lock up an important NFS server. This server then jammed until the client was physically restored by me. The fun never stops. Hopefully this won't happen again! Thanks for your patience.
