Better Alerts [as in, far more specific and just generally way better]
A couple of weeks back, we broke sign-ups. And in the most meta fashion, we learned about this because someone here had the foresight to set up an alert in Sentry to notify us if sign-ups dropped to zero. Getting alerted kicked off our incident response process. A team was formed to tackle “What broke?”, “How do we fix this?”, “How long has this been happening?”, “Are any other services impacted?”, and much more.
