Source monitoring · every feed, every day

Feed Health

Every source behind the index, probed live. Each feed is judged on two axes: reachability and content freshness — a source can return HTTP 200 while silently serving old data, so freshness is measured against the newest record timestamp, not the response code. Independently, a daily ledger confirms every feed healthy on at least a {window}-day cadence; any feed slipping past that window surfaces as DUE.

Probing all feeds…

Reading this page live — reachable and newest content within the feed's expected cadence · stale — reachable but newest record older than its cadence (the silent failure mode this page exists to catch) · delayed — probe timed out · unavailable — unreachable or malformed. Reach-mode feeds (event-sparse sources like SEC filings) are judged on reachability with a long content backstop, so quiet weeks don't false-alarm. Confirmation OK means the feed was observed fully healthy within the last 30 days; ledger updates nightly. Probe data refreshes every 60 seconds.
