We will be taking system time at 6 AM CST on March 11th, 2017. The plan is to migrate the server smile to new hardware – with an SSD disk and “real” HW (smile is a VM today). Some services are expected to be unaffected (email, DNS), and others will be unavailable. (HTTP, list server, SQL server, shell access, procmail). All services are expected to be restored by 9 AM CST.
