Summary of Impact: On 25th October 2023, between 11:00AM to 12:30PM (AEDT), a server outage was identified. A significant number of users encountered an "SSL Certificate Expired" warning from their browser, which inhibited their ability to access the Core Practice system.
Root Cause: Upon investigation, the expiration of the SSL Certificate was traced back to an unsuccessful automatic renewal. The failure in automatic renewal was attributed to modifications in the validation process of approved domains by our Certificate Authority provider. While we aimed to reduce the outage duration, this incident was exacerbated when it was discovered that the certificate had not been successfully installed across multiple servers. Fortunately, we managed to utilize redundant servers on standby to meet the user demands.
Mitigation: The Core Practice team is dedicated to improving our infrastructure to prevent such issues from recurring. We are currently incorporating Application Gateway technology to mitigate the risks tied to certificate management.
