UPDATE: Closing this old Service Alert.
On Wednesday, March 6 between 8 and 9am, we will be making configuration changes to a number of web servers to protect against a security vulnerability.
Deploying the configuration change will require restarts, which could cause an interruption in service of a few minutes. The services potentially affected include: Confluence, Cubmail, DARTS, Dokuwiki, Doris, ECRT, HyperContent, Mailman, Sundial, Wind, and websites hosted on our main webservers.

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:
