Due to a NFSv4 issue with our main NFS server (nfs4.cims), some services (such as mail) were unavailable earlier this afternoon. While these services have come back online since, we will need to perform an emergency reboot of the NFS server tonight.  Remote login and IMAP services will be unavailable between midnight and 2am.  We apologize for the short notice and the inconvenience. Should you have questions regarding this outage, please contact helpdesk@cims.nyu.edu.
