After the migration of cinna.cc.gatech.edu's services to cinnamon.cc.gatech.edu (http://support.cc.gatech.edu/utilities/alerts/cinna-cc-gatech.edu), the YP master server burdell.cc.gatech.edu retained a cached reference to cinna and hung waiting for the availability of file systems from that host. This would have affected CoC UNIX password resets. Burdell was rebooted at 9:45 AM, Friday, March 20, 2009, to clear references to the old file systems. It was again providing services at 9:55 AM, March 20.
