Observability has a blind spot, and for most teams it sits at the network layer. You instrument your services, scrape metrics into Prometheus, ship logs somewhere searchable, and build dashboards that tell you when something is wrong inside your infrastructure. But the routing that carries traffic to and from that infrastructure often lives entirely outside the stack, watched through separate tools that do not talk to your alerting. This piece looks at why routing belongs in your observability pipeline and what it takes to get it there.

External monitoring is only useful if you can trust what it tells you. Synthetic checks, uptime probes, and content verifications all run from outside the perimeter, hitting public endpoints the way a real user would. When those checks return clean, honest results, teams catch problems early. When they return noise - false outages, phantom latency, blocked responses - the whole practice degrades into alert fatigue. And a common, under-appreciated source of that noise is the IP address the checks run from.
