Today, May 14 2013, at 12:45PM we will be temporarily removing one of the home directory servers from service to address some reliability issues. Users with home directories under /nfs/13 will experience a brief disruption in service. Logins will likely fail, and jobs will not run for these users.

We expect this outage to last for 15-30 minutes.
