Resolved after 11 hours 7 minutes, affecting CMS, on May 28, 2026.
**Incident Start Time:** 19.49 BST **Incident End Time:** 22.03 BST **Issue Summary:** An incident occurred within Dynamic Content that required a rollback to a previous version. In the Development Tab of Dynamic Content, search indexes were returning zero records. **Root Cause:** The issue was introduced in a recent Dynamic Content release, which introduced a new Content Security Policy \(CSP\) header. This header unintentionally blocked Algolia search index requests, resulting in searches returning no records. **Corrective Actions:** * Improve validation and regression testing around CSP-related changes to ensure third-party services such as Algolia continue to function as expected. * Whitelist the security headers in a future release.
