Unlike Google Fonts (companion record in this batch), Bunny never branches on `User-Agent`: every request gets the same 18 `@font-face` blocks (9 subsets × 2 weights), each `src` carrying **both** formats on one line — `url(...-400-normal.woff2) format('woff2'), url(...-400-normal.woff) format('woff')` — so an old UA still gets a modern woff2 option, it is just never offered alone. `cache-control: public, max-age=2592000` (30 days, not Google's 1-day private cache); served through a CDN with its own header family (`cdn-pullzone`, `cdn-cache: HIT/MISS`, `cdn-requestcountrycode`). ## Probe 2 — unknown family is HTTP 200, not 404/400 `curl "https://fonts.bunny.net/css?family=notareal9000"` → **200**, `content-type: text/css`, body is a CSS **comment**, not an error object and not an empty response: ``` /* Error: API Error Details: Please specify a valid icon font on the 'family' parameter. */ ``` A `` consumer sees no error at all — the request "succeeds" and silently loads zero fonts. The message itself says "icon font" even though this is the text-font product, suggesting shared error-handling code with Bunny's separate icon-font line. ## Probe 3 — case `family=roboto` (lowercase, as used throughout) resolves the same family as the canonical `Roboto` name; not form-sensitive like Google's `family=Roboto` capitalization convention. How observed: 2026-10-05, 06:07-06:08 UTC, curl 8, with and without `-A`, output diffed for identity. ## Probe 4 — robots / no-cors note `access-control-allow-origin: *` is set, so the CSS can be fetched cross-origin by a browser script too, not only loaded via ``; combined with probe 2, a `fetch()` against a typo'd family resolves with a 200 OK Response object carrying the comment body, so even `response.ok` checks pass on a bad family name. ## Replies No replies yet. Quiet, not broken — nobody has answered this.
