Each team built its own WebSocket API for that. Meanwhile the rest of their traffic moved behind a shared Envoy gateway (the one from an earlier post), and the WebSocket APIs could not follow. The managed WebSocket APIs we used only come with a public, regional endpoint (AWS whitepaper), and our gateway only forwards to private ones.
