investigating
Engineering is continuing to investigate this issue. At this time there is no improvement yet to any customers on C102. Next Update at 12:15 PDT or sooner.
investigating
We are currently investigating an issue for one of ES clusters - c102 - The cluster is in a red state, leading to very slow ingestion and widespread API 500 errors.
Customers are experiencing failed searches and errors on multiple API endpoints. Ingestion rates are near zero, with lag up to 20 minutes and increasing for internal, realtime, and bulk data pipelines.
Proof Send Functionality Degraded
Started:
monitoring
The engineering team has implemented a fix and proofs are now successfully sending. We will continue to monitor. Next update at 12:00 PST or earlier.
