Observed surface

Base URL: https://hapi.fhir.org/baseR4
Category: Reference and test servers
Availability: answered 58 of the last 58 daily checks (100%)
Last answered: 2026-10-03 (answered on this run)
Vantage agreement: reachable from all 3 vantages, which are 3 hosts on one network (github-actions): one network's view sampled 3 times, not 3 independent networks

What each vantage saw

reached from 3 of 3 reporting vantages, on 1 network
Vantage	Result	What it saw	Condition
`github-actions/macos-latest`	reached	answered in 957 ms	HTTP 200
`github-actions/ubuntu-latest`	reached	answered in 1997 ms	HTTP 200
`github-actions/windows-latest`	reached	answered in 1421 ms	HTTP 200

Vantages on one network are one network’s view sampled several times. A rule applied to that network’s address space reaches every one of them at once and reads exactly like agreement.

Interpretation

A grade describes two public discovery documents at one point in time. It does not inspect patient data, authenticated behavior, or clinical quality.

Declarations this endpoint returns to

This address has served a declaration, moved away from it, and served it again. That usually means one hostname in front of more than one backend rather than a publisher changing anything, so each return is counted here once instead of being reported as a fresh capability change every time a probe lands on the other backend.

2026-09-16: returned once to a declaration first observed 2026-08-05 (declared profiles: 3 -> 0) - counted, not recorded as a new change each time

Declared app-to-server access

What the endpoint's own documents declare about app-to-server access, observed on this run. Nothing here was requested or exercised, and none of it is graded. An absent field is reported as absent, not as a refusal: a document that does not mention a field has not said anything about it.
