+## 🐛 Fixes
+
+### Fix spurious `REQUEST_RATE_LIMITED` errors when no rate limiting is configured ([PR #9034](https://github.com/apollographql/router/pull/9034))
+
+Under sustained load, the router could return `REQUEST_RATE_LIMITED` (429) errors even when no rate limiting was configured. An internal queue had an implicit limit that could trigger load shedding, even if the queue was not _actually_ overloaded.
+
+This fix removes that implicit limit, so requests are shed only when the queue is genuinely full. The queue still has explicit limits to ensure quality of service.
