    On Monday, July 25, the certification authority HARICA will revoke some of its previously issued SSL/TLS certificates due to a compliance issue identified in the certificate profiles.

    The Information Technology Department is replacing affected certificates on an ongoing basis to prevent potential service disruptions.

    If you have ordered a HARICA certificate, please contact the IT Helpdesk to check whether your certificate needs to be replaced.

    If you experience any problems with a certificate or secure connection when using any of the services after July 25, please also contact the Helpdesk.
