How to read it

An observation says the endpoint answered a request for its public /metadata document, not that what came back was any good. A declaration change is a recorded difference in what its CapabilityStatement says about itself; each endpoint's page lists them with their dates, and lists separately the declarations it has gone back to rather than counting a backend alternating as a run of releases. The grade is a separate question and lives on each endpoint's scorecard. A day with no observation is a day this project recorded nothing, which happens when a scheduled run does not complete; it is never evidence about the endpoint.

Reachability is measured from three hosts on one provider's network. One of them reaching an endpoint settles that it is up; all three failing settles only that it was not reached from there. See how we grade.
