Reachability of each upstream the dashboard pulls from, probed live. up = serving · auth required = endpoint live, needs a key · rate limited = live but throttling us · degraded = reachable but erroring · blocked = the source refused our request (region/firewall) · down = no response at all · retired = we stopped calling it on purpose (a by-design block, not an outage). Distinct from Data Freshness (are the cached Data Fact Containers recent?).
Freshness of every cached Data Fact Container the dashboard depends on (are they recent?). Distinct from Upstream Sources (are the APIs live right now?).
