On Thursday, April 23, 2009, between 7:00 PM and 10:30 PM, the BES and Exchange servers will be patched. 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 servers are restarted. Email received during this time will be queued and delivered once services are restored. BlackBerry phone services will not be affected.
