Understand an edge
check at a glance
This page illustrates how one endpoint can be checked from several edge locations and reported with the same fields. Locations, timings, plans, and results are examples; no probe runs from this page.
- example endpoint
GET /health- example origin
- Seoul
- example cadence
- 10 s · 28 locations
GET /health → inspect the response
Illustrative workflow only — this page does not create an account, run a check, or collect a destination URL.
How an edge check is mapped
The diagram separates an endpoint, distributed checking locations, and the metrics returned to a monitoring system. It is a conceptual route, not a map of operating facilities.
Check from the edge
A useful check identifies where it ran and which part of the response was measured, so results can be compared fairly.
Check the response, not only reachability
A useful workflow can compare response content, status, certificate expiry, and timing instead of treating a reachable address as success.
Keep the reporting fields consistent
The example keeps endpoint, location, time, and response fields together so they can be handed to an existing monitoring workflow.
One example frame, many locations
This table shows how an endpoint, DNS, TLS, response time, and a percentile can be read together. Its values and locations are illustrative.

| NRT-02 | Tokyo | 2.1 | 7.1 | 28.6 | 31.2 |
| SIN-01 | Singapore | 2.4 | 8.2 | 34.0 | 37.5 |
| SJC-04 | San Jose | 3.0 | 9.6 | 88.4 | 94.7 |
