AZURE TRAFFIC MANAGER / LEARNING LAB

One DNS decision.
Two regional endpoints.

You are viewing a regional Azure Container App, not a Traffic Manager proxy. Follow the signal from DNS selection to probe health to real application work.

Live status refreshes every 3 seconds from this regional hostname.

01 / DNS

Selection is not forwarding

Traffic Manager returns DNS answers. Cached answers can outlive a routing change. This regional URL stays in its region; refreshing it does not re-test Traffic Manager selection.

02 / PROBE

Health is a contract

/health is the Traffic Manager monitor signal. A green probe is only as useful as what it checks.

03 / WORK

Test what users need

/work simulates a user operation. In false-positive mode, the probe returns 200 while useful work returns 503.

Compare the four modes

Mode/health/workLesson
healthy200200Healthy probe, successful work
unhealthy503503Application failure is visible
dependency-failure503503Dependency-aware health is visible
false-positive200503Shallow probe hides failed work

ACA platform probes /live and /ready stay at 200 in every mode so the simulated failure remains observable. Changing a mode requires an authenticated management-plane deployment; there is no public toggle.
