        significant if you have many PS servers. We are aware of this issue and
        working on fixes, for now we suggest using the legacy optimizers when
        using `ParameterServerStrategy`.
    *   **Timeout or performance loss.** We don't anticipate this to happen, but
        if you see such issues, please use the legacy optimizer, and file
        an issue in the Keras GitHub repo.

A security issue was discovered in kube-apiserver that could allow an attacker controlled aggregated API server to redirect client traffic to any URL.  This could lead to the client performing unexpected actions as well as leaking the client's credentials to third parties.
