Site status, pasted as the checks found it

Nothing on this page is hand-written: the server checks every endpoint and the as-of date of ten datasets each hour, writes the result verbatim to /api/v1/status.json, and the page reads it live. A failed check shows red, with no human polish. Below: this site's operations and security disclosure.

Endpoint health checks
Fetched one by one from the server via the public domain — the full Caddy chain, not an internal shortcut.

Data freshness
Each dataset's as-of date against its cadence. Event-driven datasets revise only on new issues, maturities or corrections — a growing day count is not an outage.

Operations & security disclosure

ItemDisclosure
OperatorSpreadBench is an independent data-benchmark project run by Brian Tian (attribution and citation format on the citation page). It is not a corporate entity, issues no securities and provides no investment service.
Data boundaryOnly public data is aggregated: SEC EDGAR filings, the US Treasury curve, and FRED (via the St. Louis Fed) OAS references. No licensed data, no secondary trades (FINRA TRACE not licensed), no CDS. Red lines: no credit ratings, no investment advice.
AccountsThere are none. All content and APIs need no registration, no login and no API key (until v0.3.0). Hence there is no password store and no account data to leak.
What this site collects(1) Anonymous in-page events: page path, language, referrer — no personal identifiers. (2) Standard server access logs, with sensitive headers (Cookie / Authorization / X-Api-Key) stripped before writing to disk. (3) IP addresses are used only for anti-abuse rate limiting and country-level statistics — no profiling, no linkage to any identity. No third-party advertising cookies, no cross-site tracking.
PaymentsPaid products (the GRVI data archive etc.) settle via Alipay or USDT through payment channels; this site never stores card data. Order records hold contact details and the purchased SKU only.
Service surfaceStatic site + read-only APIs; the only write path is order checkout. The admin path is disallowed in robots.txt.
Incidents & changesEvery product and API change is logged in the changelog (line by line); data-convention changes go through methodology §11 with a version bump. This status page does not duplicate them — it reflects machine checks only.
ContactBroken endpoint or data anomaly: hi@spreadbench.com (data errata answered within 5 business days per methodology §13).
