Why do two directories disagree about the same endpoint?
Answered from the issue named below, as published on its date. A later issue is a later answer, at its own address.
The answer
Across 21–31 August 2026 we recorded 29,022 observations and compared 7,225 independently graded endpoints with 402index's health labels.
(2) The OBSERVED population: every endpoint on probe402's seed that produced at least one graded observation inside the sealed window of 21–31 August 2026, joined to a third party's published label for the row whose address is the exact route we probe; an endpoint we did not grade, or whose label read failed, is outside every joined figure and is counted rather than dropped.
402index's
healthylabel means the endpoint answered HTTP 402 within its timeout; MCRI tests whether the response contained a payable quote.

What this does not say
- Third-party figures are those providers' own published numbers, quoted with their own denominators and the date we read them. They are not our measurements of those providers.

| The join behind the issue's opening finding: every independently graded endpoint of the sealed window set beside one fresh dated read of the health-label surface, covering all 1,588 hosts we cover, with that surface's own last-checked stamp carried per row. | 158940a9769dd5b44614f9f9201235f708388e7b0fdae0a589e3fd063798be1a |
