Smart(er) Origin Service Level Monitoring

What this post added

This post introduces Origin Error Rate notifications, a significant enhancement to website availability monitoring. It moves beyond simple 'origin down' alerts to sophisticated anomaly detection using Service Level Objectives (SLOs) and burn rate calculations. This allows for proactive notification of elevated 5xx errors from origin servers, even when they are not a complete outage, by analyzing error rates against user-defined SLOs and employing both short and long-term indicators to minimize false positives and ensure timely alerts.
