On Wed 26-Feb, we are making a large change to how NFS is mounted in Cloud Services https://gerrit.wikimedia.org/r/c/operations/puppet/+/571821. This will impact any Cloud VPS projects that mount NFS for home directories, project directories and scratch, including Toolforge.  During this change, NFS will become unresponsive for a short time. Some NFS clients will recover on their own with little impact. Where needed, WMCS will reboot or remount NFS clients. This change will improve future NFS management and hopefully reduce future disruptions from maintenance.
