Azure Front Door is Microsoft’s global edge - CDN, WAF, and layer-7 load balancing at hundreds of points of presence. It is often the first Azure service your customers touch, so Front Door incidents look like a total outage even when origins are healthy. Because it runs at the edge, problems tend to be geographic or configuration-propagation-driven.
Elevated 5xx rates at a subset of edge locations or in specific geographies
Configuration and WAF-rule propagation delays or failures
Health-probe misfires failing over traffic away from healthy origins
Global routing events - a bad config push propagating to the edge fleet
