This check runs on a real home internet connection in United States — a small hardware probe plugged into an ordinary household router, not a cloud server. It sees the web the way a person there does: the local ISP's routing and DNS, national peering, and any geo-blocks or filtering that apply.
Right now 34 measured homes across 11 providers in United States feed this check. Latency below is the median round trip from those homes, with each home's own Wi-Fi hop subtracted.
| Provider | Latency | Homes |
|---|---|---|
| Cincinnati Bell Telephone Company LLC | 13 ms | 10 |
| Comcast Cable Communications, LLC | 19 ms | 5 |
The check fires from United States alongside nodes in 32 other countries, so a single run shows you the difference between "United States has a problem" and "the site is down everywhere". How it works →
