+# Investigating and monitoring the health of the Registrar
+
+Sometimes, we may want individuals to routinely monitor the Registrar's health, such as after big feature launches. The cadence of such monitoring and what we look for is subject to change and is instead documented in [Checklist for production verification document](https://docs.google.com/document/d/15b_qwEZMiL76BHeRHnznV1HxDQcxNRt--vPSEfixBOI). All project team members should feel free to suggest edits to this document and should refer to it if production-level monitoring is underway.
