FAILING right now — answering HTTP 525 to plain requests.

Context: Connections hang/time out — tutorial <img> tags stall silently.
What we check: GET https://via.placeholder.com/150 — a plain, keyless request from Cloudflare's network with an honest bot UA, exactly what a tutorial curl or an <img> tag experiences. OK = HTTP 2xx/3xx within 8s. No retries, no cookies, no API keys.
If via.placeholder.com is failing (or you're tired of finding out mid-demo), Mockbird gives you a placeholder image URL that renders (SVG: any size, colors, text, round avatars) — free, no signup:
