UMich IFS servers will be down starting at 1am Saturday, 20 November, for maintenance and are scheduled to come back up at 6am. Servers will be down again Sunday morning from 1am to 6am. From ITD’s outages page:
The IFS team will be taking the IFS fileservers out of service during the usual maintenance window this
weekend to upgrade software and correct some
consistency issues.
The IFS team expects that this will eliminate the
intermittant fileserver crashes of the past several months.
