The situation
Code Nexus's feed responds through the lab's direct-address test, but its normal name fails to resolve. Jax needs an accurate update for creators. Priya asks you to identify the observed failing layer, record what each test establishes and escalate to the team that owns it.
What you'll learn
- LAN vs WAN, IP addresses, DNS, ports, client and server.
- HTTPS and what each hop in a request does.
- Where a front-line responder's job ends and a platform team's begins.

What you leave with
You walked the request outward, found DNS was the first failing hop, ruled out the alternatives with checks against known-good examples, escalated to the right team, and gave creators something true.
