Cambium Networks experienced intermittent failures affecting customers using the Google CBRS SAS service, with impacted devices unable to obtain new grant approvals and entering an unauthorized/idle state with no active spectrum grants. The outage lasted 3.1 hours before error rates dropped and devices came back online. The incident was resolved through collaboration with Google to address the grant termination issues.
