We've improved the metric ingestion delay time and are working on additional fixes to bring it down to expected range. Customers can currently expect a delay of 2 to 5 minutes before their test run metrics show up (after starting a test).

We are experiencing intermittent delays with secondary metrics processing for k6 Cloud test runs due to heavy load. We don't expect any data loss or impact on user runs, but results may take longer time to appear in UI.
