On Thursday, January 29, 2009, between 6:30 PM and 10:30 PM, the latest operating system patches will be applied to all of the email servers as well as to the front-end and ISA servers in the production Exchange environment. This will affect CoC faculty and staff who use Exchange email or calendaring services and those with a CoC-issued BlackBerry. Though significant downtime is not expected, users may experience minor interruptions while the email, front-end servers, and ISA servers are restarted. Email received during this time will be queued and delivered once services are restored. BlackBerry phone services will not be affected.
