    As we shared earlier this month, Columbia University Information Technology (CUIT) is upgrading the storage capabilities and supporting infrastructure for several of the key systems and applications across the University. As a result, some websites and other key applications will be intermittently unavailable. Please be sure to save and complete your work as much as possible prior to this window.


    We have prioritized the upgrades so that we can restore service to the most critical applications as quickly as possible, and a list of the business-facing critical and non-critical applications (PDF) that will be affected is available on our website.


    Critical applications will be intermittently unavailable beginning at 7:00 p.m. Friday, June 19, through 5:00 a.m. Saturday, June 20.  


    Non-critical applications will be intermittently unavailable beginning at 5:00 p.m. Friday, June 19 through 5:00 p.m. Saturday, June 20.


    We recognize that these downtimes may pose an inconvenience to you; thank you in advance for your patience. Ultimately, the upgrades will benefit the entire Columbia community with more robust, reliable, and secure technology.


    If you need help during the planned downtime or have questions, please contact the CUIT Service Desk at (212) 854-1919.
