RESOLVED 9 months ago - at 07/21/2025 04:31PM

Between 11:40 - 15:30 UTC, we experienced issues with elevated load and lock contention on the primary database in the US region leading to delays in data ingestion, alerting notifications, and webhook integrations. The database issue was caused by a long running REINDEX on the database in combination with elevated levels of traffic.

The issue was resolved and everything is operating as expected.
