    Cogent, our primary Internet provider, is performing network maintenance on Wednesday June 1st, from 1:00am until 2:00am.

    During the maintenance window Internet traffic will be automatically routed over our backup Internet connection, so no loss of network connectivity is expected.  However, users may experience very brief periods of slowness during failover to the backup connection.

    If clients continue to experience issues after the service-interruption hours, please contact the CUIT Helpdesk at:

  • Network - Ethernet

    We are currently experiencing issues with one of the circuits to our secondary gateway at Syracuse.  Until the issue is resolved, we will be without a redundant connection to the secondary switch.  There should be no noticable impact to services.

    We have opened a ticket with our service provider and are waiting on an update. 

    UPDATE: Our redundant link to Syracuse has been restored. The circuit was affected by a cut in Ithaca, NY and could not be immediately repaired so our link was migrated over to spare fibers.
