/**
 * [Joshen] JFYI before we go live with this, we need to revisit the migrations section
 * as I don't think it should live in the ServiceStatus component since its not indicative
 * of a project's "service". ServiceStatus's intention is to be an ongoing health/status check.
 *
 * For context, migrations are meant to be indicative for only when creating branches or projects
 * with an initial SQL, so "healthy" migrations just means that migrations have all been successfully
 * ran. So it might be a matter of decoupling "ready" state vs "health checks"
 * [Edit] Now that migrations are only showing up if the project is a branch, i think its okay for now
 *
 * [Joshen] Another issue that requires investigation before we go live with the changes:
 * We've removed the isProjectNew check in this component which we had that logic cause new
 * projects would show unhealthy as the services are still starting up - but it causes a
 * perceived negative impression as new projects were showing unhealthy, hence the 5 minute
 * threshold check (we’d show “Coming up” instead of “unhealthy” if the project is within 5
 * minutes of when it was created). Might be related to decoupling "ready" state vs "health checks"
