Resolution

Redirecting BigQuery's service account to a different GCP project with on-demand billing resolved the problem.

Affected Users

Users in Prod1 and Prod2 were impacted. Only the Perspectives and Dashboards features were affected, while the rest of CCM operated without issues.

RCA

Google's BigQuery employs slot AutoScaling to enhance slot availability for better performance. An incident with BigQuery hindered the slot AutoScaling functionality. Since CCM's perspectives and dashboards rely on BigQuery, the incident impacted their query response times.

Monitoring

Harness has recently implemented a workaround for the majority of customers which should restore CCM Perspectives as well as Custom Dashboards. Our primary upstream provider(GCP) however, while showing some signs of recovery is still encountering issues. Harness will continue to provide status updates as we closely monitor the workaround we have put in place to mitigate issues related to CCM Perspectives and Dashboards until the incident is fully resolved.

(Note: Existing GCP/CCM connector validation/test functionality will error out due to the workaround in place, but does not affect product functionality)
