Question 1

Which platforms does this network reachability checker test?

Accepted Answer

It tests 17 platforms across 4 categories: AI Tools (ChatGPT, Claude, Gemini, Perplexity), Streaming & Music (Netflix, YouTube, Spotify, Twitch, Disney+), Social & Video (TikTok, X/Twitter, Instagram, Facebook, Reddit), and Developer & Others (GitHub, Discord, Steam, Google).

Question 2

How does the tool determine if a platform is reachable?

Accepted Answer

For each platform it fires a no-cors fetch request to that service's domain (using its favicon.ico or a generate_204 endpoint for Google/YouTube) and marks it reachable or blocked based on whether the request completes within a timeout window you set to 4, 6, or 10 seconds — 6 seconds is the default.

Question 3

Do I need to install anything or sign in to run the test?

Accepted Answer

No. The checker runs entirely in your browser — click Run Test and it fires reachability checks against all 17 platforms simultaneously, showing a green or red status dot for each with no login, install, or extension required.

Question 4

Can this tool tell me if my VPN is actually unblocking specific sites?

Accepted Answer

Yes — run the test with your VPN or proxy connected and compare the green (reachable) versus red (blocked) dots per platform. Because it checks 17 individually named services rather than just general internet connectivity, it can confirm whether a VPN is successfully unblocking specific platforms like ChatGPT or Netflix versus others that remain blocked.
