Is Cognite Down?

The performance degradation affecting Data Modeling search and indexing in **westeurope-1** has been fully resolved. Syncer capacity has been restored, cluster health metrics have returned to normal, and all indexing backlogs have cleared. Search, aggregation, and data modeling queries are functioning as expected. We are continuing to monitor the services to ensure ongoing stability. --- [2026-09-23T19:18:00Z] (monitoring) • **Problem:** The Propertygraph Elasticsearch cluster in **westeurope-1** experienced degradation, temporarily entering yellow and red states. • **Impact:** Customers with projects in `westeurope-1` may experience delays in newly created instances appearing in search results, along with elevated latency for search and aggregate queries affecting data modeling indexing (`datamodelstorage`) Core data storage is unaffected. • **Root Cause:** A syncer update triggered concurrent restarts across syncer deployments simultaneously, overwhelming the search master nodes with high-volume reads. In addition, an search pod encountered a PVC mount failure during rolling updates. • **Status & Mitigation:** Mitigation steps have been applied. Our engineering team scaled down the syncers to allow the cluster to recover to a healthy green state, subsequently re-enabled the synchronizers in stages, and resolved the PVC volume mount issue. The cluster is stabilizing, and our team is actively monitoring system performance and recovery. --- [2026-09-23T17:45:19Z] (investigating) We are currently experiencing performance degradation affecting search and data modeling indexing services in the **westeurope-1** region. **Impact:** Search and aggregate queries may experience elevated latency, and newly created instances or index updates may take longer to appear in search results. Core data storage is unaffected. Our engineering team is actively investigating the issue and working on mitigation steps to stabilize the service. We will provide updates as more information becomes available

Service has been restored. The Elasticsearch cluster in westeurope-1 has stabilized, and search, aggregation, and data-modeling indexing are operating normally. --- [2026-09-23T00:08:09Z] (monitoring) The Elasticsearch cluster in **westeurope-1** became overloaded and entered a red state. This degraded search and data-modeling indexing. search and aggregate requests could be slow or fail, while new instances and index changes could take longer to appear. **Root cause:** A rollout restart of **pg3** overloaded the Elasticsearch cluster. **Fixing status:** The incident is now in **Monitoring**. Engineering team paused some background synchronizers to reduce load, allowed Elasticsearch to stabilize, and then started re-enabling the synchronizers. The fix was marked as applied. --- [2026-09-22T21:10:57Z] (investigating) We are currently investigating performance degradation and high latency affecting search and data modeling services in the **westeurope-1** region. **Impact:** Search and aggregate requests may experience high latency or temporary failures. Newly created instances or index updates may take longer than expected to appear. **Status:** Our engineering team is currently scaling down background syncing processes to reduce load and restore cluster stability. Further updates will be posted as soon as they are available.

The performance degradation affecting Data Modeling search and indexing in **westeurope-1** has been fully resolved. Syncer capacity has been restored, cluster health metrics have returned to normal, and all indexing backlogs have cleared. Search, aggregation, and data modeling queries are functioning as expected. We are continuing to monitor the services to ensure ongoing stability. --- [2026-09-22T10:31:57Z] (monitoring) The underlying cluster in `westeurope-1` has stabilized, and search and aggregate queries are functioning normally. Indexing pipelines are currently processing the remaining backlog, so some users may still see slight delays in newly ingested data appearing. We are monitoring the recovery closely. --- [2026-09-22T10:08:52Z] (investigating) We have identified an issue affecting search and data modeling indexing in the `westeurope-1` region. Users and automated pipelines in this cluster may experience delays in newly ingested data or schema updates appearing in search and data modeling views. Querying existing indexed data and other CDF services remain operational. Our engineering team has implemented traffic-shedding and resource adjustments to stabilize the underlying cluster, and indexing throughput is beginning to recover. We are closely monitoring cluster health and will provide our next update soon,
