We've identified an issue within our Kubernetes internal networking component, causing intermittent 502 errors for a subset of applications. Restarting affected applications often provides a temporary resolution, as they typically migrate to updated nodes.
Our team is actively investigating the root cause. Concurrently, we are proceeding with planned infrastructure maintenance, which is expected to fully resolve this issue upon completion.

We appreciate your patience as we work towards full stability.
