Helium login node down

One of the three Helium login nodes is down. It will be removed from the DNS round-robin shortly (may take up to 24 hours). In the meantime, if your login to helium.hpc.uiowa.edu fails try specifying a login node explicitly. The two that are currently up are:

helium-2.hpc.uiowa.edu
helium-3.hpc.uiowa.edu
