Impact of the change on users:
IronPort access may not be available during the maintenance window. End users can log into IronPort to access their user quarantine, safelist, and blocklist; however, they will not be able to log into the system to access those items. Also, releasing messages from the user quarantine happens through this system so they will not be able to release messages from quarantine until the upgrade is complete.
Reason for the change:
ITS is upgrading and applying patches to the server. (ID # 245274)
