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 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.
