Contacting Cora Support
We always recommend raising, tracking and responding to tickets through the Customer Helpdesk at https://cst.corasystems.com. This matters more than usual during the incident.
If your organisation’s email is affected, you may not receive ticket notifications from us, and replies you send by email may be delayed. The helpdesk shows every update on your tickets as soon as it is posted.
Updates
We are monitoring the situation and will update this article if anything changes for your Cora services.
