Degraded REST API Availability
Status: investigating
We are continuing to investigate an issue causing approximately 35% of REST API requests to fail. Based on our current understanding, requests are not consistently reaching the application layer, resulting in failed requests returning HTML responses instead of the expected API response format. We are actively investigating the issue and will provide another update as soon as more information is available.
