 This document explains the details of API service startup and shutdown behavior, in particular related to:
+- Zero-downtime deployments
 - Proposer API
  - Needing data before being able to handle `getPayload` requests (known validators)
- - Draining getPayload and other requests before shutting down

+- We've added two endpoints: `/livez` and `/readyz` (per [k8s docs](https://kubernetes.io/docs/reference/using-api/health-checks/)) in [#469](https://github.com/flashbots/mev-boost-relay/pull/469):
 - On startup:
  - `/livez` is immediately available and positive, and will stay so until the service is shut down
  - `/readyz` starts negative, until all information is loaded to safely process requests (known validators for the proposer API)

 The proposer API needs to load all known validators before serving traffic, otherwise, there's a risk of missed slots due to `getPayload` not having all the information it needs to succeed.
