If Claude is not working
- Open the site over mobile data instead of Wi-Fi: if it works, the problem is your home network or router.
- Switch DNS to 1.1.1.1 or 8.8.8.8 and flush the DNS cache (ipconfig /flushdns on Windows).
- Try another browser or a private window: extensions and cache can get in the way.
- If the site fails only from your country while working elsewhere, it is blocked there, and changing browsers will not help.
AI services are sometimes unavailable from particular countries by the provider’s own decision, not because of an outage.

Questions
Why does Claude not work for me when the check says it is up?
Then the service is fine and the problem is on your side: your home network, router, DNS, browser or provider. Try the steps below.
How can I tell whether Claude is blocked?
If probes in one country get timeouts, connection resets or a provider block page while other countries open the site, it looks like a block.
How fresh is the result?
It runs every time you open the page or press Check: it is live, not cached.
