UniSuper experienced a major outage affecting 620,000 members due to a deletion incident on Google Cloud without any disaster recovery recourse.
Despite regional data duplication, an internal Google error led to data loss in both regions, highlighting the importance of external disaster recovery facilities.
UniSuper's additional backups with another provider helped minimize data loss, emphasizing the necessity of multiple backup strategies.
While Google referred to the incident as an isolated occurrence, concerns persist over the lack of transparency and potential operator error in the system.
