Incident Timeline
Monitoring
The cluster remains stable, and we are continuing to monitor it.
Oct 1, 2026 at 8:13 AM UTC
Monitoring
We have increased isolation in the storage layer for the impacted region to provide greater amounts of resilience and to allow for faster recovery. We are continuing to investigate heightened memory consumption and page faults within the storage layer. Query success rates and response durations have returned to normal levels. We will continue work to increase the resiliency of this region over the next 24 hours and will carefully monitor for any increase in query latency.
