A static, single-page tool that checks whether your network can reach popular international websites (Google, YouTube, Twitter, Telegram, Instagram, GitHub, etc.).
Runs entirely in-browser — no server, no data collection.
Uses favicon image probes with cache-busting to detect connectivity. Choose between a 3-second or 5-second timeout depending on your network speed.
Host index.html anywhere static — GitHub Pages, Netlify, a simple HTTP server, or just open it locally in a browser.
