On Wednesday, June 24, 2009, between 7:00 PM and 9:00 PM, routine maintenance will be performed on the CoC Exchange email infrastructure. 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 a minor interruption 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.
