Check if a website works from Czechia

This check runs on a real home internet connection in Czechia — a small hardware probe plugged into an ordinary household router, not a cloud server. It sees the web the way a person in Czechia does: the local ISP's routing and DNS, national peering, and any geo-blocks or filtering that apply there.

Check

Why check from Czechia specifically?

• Geo-blocking — many sites serve different content per country, or none at all. A check from Czechia shows what Czech visitors actually get.
• Regional outages — CDNs and ISPs fail locally. Your site can be up globally and still unreachable from Czechia.
• Real latency — the response time measured here includes the Czech last mile, not a datacenter backbone.

The check fires from Czechia alongside nodes in 11 other countries, so a single run shows you the difference between "Czechia has a problem" and "the site is down everywhere". How it works →
