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. Distinct from Data Freshness (are the cached Data Fact Containers recent?).
