What happens when you run a check
- You type a domain. The request joins one global queue — the whole network fires at most one check every 20 seconds, so target sites feel a gentle tap, never a flood.
- Devices in different countries pick it up. Each node makes a single HTTP request, exactly the way a browser would, and measures how long the site took to answer from its own connection.
- You watch it live on the map. Every line is a real measurement from a real household. If a site is slow or unreachable in one region, you see exactly where.
Why home networks give different answers than cloud monitors
A request from a home connection travels a different path than one from a cloud server: consumer ISP routing and peering, national infrastructure, the ISP's DNS resolvers, sometimes throttling or geo-blocks. A website can be perfectly healthy for a server in a datacenter and unreachable for a household two countries away. Checking from where people actually live is the only way to see the web as your visitors see it.
Where the nodes are
The network measures from homes across four continents — from Poland, Germany and the United Kingdom to Brazil, the United States, India and Vietnam — and it grows as new operators plug in a $5 board. The network is open: anyone can run a node.
Beyond checks: the ISP Quality Observatory
The same fleet also measures its own home connections around the clock — latency, jitter and packet loss to well-known anchors, with each home's Wi-Fi hop subtracted so the score reflects the provider, not somebody's router. Aggregated daily per provider, this becomes the ISP Quality rankings: which internet provider is actually the best in a country, judged by real homes instead of a one-off speedtest. The full method — minimum samples, stated biases and all — is described in how the rankings work.
Privacy and politeness
Checks are single, browser-like HTTP requests — no scanning, no crawling, no load testing. Node locations are shown at city level only. Continuous monitoring with alerts (email, webhooks, status pages) is available as a free account.
