SSC’s network engineering team will be working with Barracudas engineers to install a second Barracuda spam appliance Friday evening between 6:30pm and 7:30pm.   SSC engineers will suspend e-mail delivery during this installation time frame.  Users will be able to send e mail during the suspension period; new email will not be delivered during the suspension period. Inbound e-mail will be stored in a queue and delivery will commence when service is resumed.  Should you have any questions or concerns regarding the shutdown please contact the SSC support desk at 62821 or email us at support@ssc.ucla.edu.
