+## Ticket Details
+### Remove Rate Limits on meshObject API in Production Environments
+**Audience:** User<br>
+
+#### Description
+The last meshStack release introduced API rate limits intended for evaluation in QA environments.
+Due to a configuration bug these rate limits were also rolled out to productive meshStacks ahead of time and without proper calibration.
+
+API consumers that were exceeding the rate limit have seen HTTP 429 responses in production environments. 
+We fixed this now so rate limiting is only active in QA environments and will separately inform you about further rollout timelines and implications for production environments.
