I don't have a way to test all the other notification mechanisms, which is something we should fix in general. For now, only PagerDuty and email have the new runbook and alertmanager URL information. Not very happy with the overall cleanliness of this, and the codebase overall, of course, but since we need this urgently tomorrow, I hope this is fine for now.
