   We are currently investigating scheduled editions that failed to publish between 05.07 - 05.52 BST

2. resolved Jun 11, 2026, 07:28 AM UTC

   A third-party provider that we use for a backend service carried out emergency maintenance earlier today, which impacted some of our services. During this period, we identified a small number of Editions that failed to Publish. We have contacted the affected customers directly and provided a workaround to allow them to proceed. We also observed degraded performance impacting DC-API during the same timeframe. Our teams are continuing to monitor the situation closely while we work with the provider to understand the full impact and prevent any recurrence.

3. postmortem Jun 23, 2026, 09:59 AM UTC

   **Incident Start Time:** 05.07 BST **Incident End Time:** 05.52 BST ‌ **Issue Summary:** An incident occurred with one of our back end databases. This caused degraded performance to DC-API and some Dynamic Content Editions were in a stuck status. ‌ **Root Cause:** Some inefficient queries to our back end database caused our primary node to fail over to our secondary node. ‌ **Corrective Actions:** We have already introduced corrective mitigations with additional indexes and working with MongoDB we have further improvements planned.
