This check runs on a real home internet connection in Vietnam — 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 1 measured home across 1 provider in Vietnam feed this check. Latency below is the median round trip from those homes, with each home's own Wi-Fi hop subtracted.
No provider in Vietnam has reached the 5-home threshold yet — the check still runs, the ranking unlocks as more homes join.
The check fires from Vietnam alongside nodes in 24 other countries, so a single run shows you the difference between "Vietnam has a problem" and "the site is down everywhere". How it works →
