  • Network - Load Balancing
    05/21/2013 - 11:00pm to TBD

    Tonight (5/21/2013) starting at 11:00pm EDT, CUIT will perform emergency maintenance on the CSM network load balancers, to address performance issues reported today with sending mail through send.columbia.edu and querying LDAP.

    The CSM service uses a redundant architecture and the scheduled work will avoid disruption as much as possible.

    However, any services using CSM network load balancing may be impacted, including the following services: Exchange, Cubmail, Cyrus, DIA, Ingo, Infoed, CUNIX, LAMP, Wind, wwwapp, Sundial and others.

    During the maintenance, on-going sessions of load-balanced applications might be disrupted. The disruption might be momentary, or could require that clients re-initiate sessions.

    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:
