## Updates from Grafana Cloud
### 2026-07-02 18:10 UTC: identified
Queries with drop \_\_error\_\_, including log volume histogram queries (the queries that generate the histogram visualization in Grafana), are failing due to a bug with series limit checks.
The Root cause has been identified, and we are working on a fix.

### 2026-07-02 20:16 UTC: identified
We are continuing to work on rolling back a PR responsible for this behavior. Once we have more information, we will share it here. 
Thank you for your patience.

This incident has been resolved. Thank you for your patience.
