- resolved Jan 04, 2026, 10:06 AM UTC
This incident has been fully resolved, and the service has been operating normally since the fix was implemented. The root cause was traced to an anomalous use-case for a particular CMP instance, where our assets database faced an unusual amount of load (500k asset lineage entries for a particular asset) causing delays in data replication in our Elasticsearch instances which resulted in uploaded assets not being visible, as well as slowness/504 errors in our asset public API endpoints. We have taken corrective actions and are implementing additional preventive measures to reduce the likelihood of similar incidents occurring in the future.
