Impact of the change on users:
ITS will be upgrading DNS servers during the maintenance period. Only one DNS server will be worked on at any given time. Production DNS servers will be upgraded at night, early morning, or weekends to minimize any possible impact. The server and its services will be unavailable for a few minutes during the reboot.
Properly configured DNS clients (i.e., more than one DNS server configured) will not be impacted.
Reason for the change:
ITS is upgrading the DNS servers to fix security issues. (ID # 186878)
