Check Service Alerts

Columbia Community Members:

As you may be aware from various news sources, last night, an important software update from the cybersecurity vendor Crowdstrike reportedly included a bug that is causing instability on Windows-based systems. Crowdstrike provides services to many institutions and industries globally, including Columbia. CUIT has been working through the night and early morning hours to resolve the issues with Crowdstrike and at present has brought a significant number of services back online, but there are still more issues to resolve.

The bug only affects Windows environments; other operating systems have not been impacted.

The resolution process is manual and thus takes time, but be assured that CUIT’s full attention is on resolving the issues across our infrastructure, classroom technologies, computing labs, and desktops.  Please visit cuitalerts.columbia.edu/cuitalerts to get the latest on any service interruptions.
