    We made our LLM gateway a single point of failure. Then we tested it.

    <p><strong>TL;DR: We put an LLM gateway in front of about 40 internal services to get failover and one billing view. Then a game day showed the gateway itself was now the thing that took everything down. Here's how we ran two Bifrost replicas, what broke, and where LiteLLM and Po…
