    CUIT engineers continue to work on a problem that has been delaying mail delivery since this morning. Some of the delayed mail has been delivered already and more is in progress.

    A software misconfiguration on some of the Cyrus mail servers caused a mail delivery outage this morning starting at about 9:30AM. The misconfiguration affected 7 out of the 16 mail servers. Mail for about 40,000 customers was queued but was not delivered. No mail has been lost but some messages will be received out of order.

    On Monday, December 22nd, from 5am to 7am CUIT will be working on improving Network connectivity by adding an additional Internet Service Provider to our network. This upgrade will improve external network (internet) performance and provide additional redundancy. During this time, customers may experience intermittent issues connecting to the network services outside Columbia's network ( e.g. Google, CNN, Gmail ).

    CUIT apologizes for any inconvenience this may cause, but this action is necessary to ensure a more reliable service.  If clients continue to experience issues after the service-interruption hours, please contact the CUIT Helpdesk at:
