External data: connectivity and network quality

Public measurements from OONI, Tor Metrics, Cloudflare Radar, IODA and GreatFire, next to this location's visitor tests: when the network was disrupted, which sites show anomalies, how many people use Tor, and what a direct connection looks like.

Outages and anomalies

Nationwide outages or traffic anomalies recorded in the last 30 days, one row per source; an event that is still running pulses at its right end.

No nationwide outage recorded in the last 30 days.

Site reachability matrix

Each cell is the anomaly rate OONI probes in this location measured that day (redder means harder to open). OONI has few probes in mainland China and many of them run behind a VPN, so one or two "ok" results on a day prove nothing. Days with too few samples get a dashed outline and no verdict; read the 14-day total and the GreatFire verdict instead. The right-most column is the pass rate visitors measured in their own browsers inside this location. Our servers are abroad and measure nothing themselves.

Days with fewer than 3 measurements are not coloured. OONI probes inside censored networks often report through a VPN, so green only means that probe succeeded, not that the site is reachable directly; trust the 14-day total and the GreatFire verdict.

Tor Metrics

Tor users

Global Tor bridge users stacked by transport (obfs4 / snowflake / webtunnel, left axis); the black line is the estimated bridge users in this location (right axis). Rising bridge use usually means direct Tor is blocked.
