Open network measurements

These are existing public OONI and RIPE Atlas measurements, not probes run by Cunicula. Country summaries combine different networks and do not guarantee the same result on every connection.

OONI dedicated Tor tests produced mostly anomalous results. OONI reserves confirmed-blocked labels for web-connectivity fingerprints, so this remains an anomaly classification.

Most OONI dedicated Tor measurements were OK in the period. The anomaly and failure counts remain visible because a country aggregate is not a guarantee for every network.

About

Browser from the Tor Project routing traffic over Tor, resisting fingerprinting and enabling .onion access.

Analysis

OVERVIEW

Tor Browser routes traffic through the Tor relay network, resists browser fingerprinting and allows .onion access without an account, with its code audited by Cure53.

LIMITS

The nonprofit Tor Project has historically drawn 35 to 50 percent of its budget from US government sources including OTF, DARPA and the State Department, the same agencies whose Naval Research Laboratory originally built the underlying technology for intelligence communications.

USEFUL FOR

For people who want relay-based traffic routing and .onion access and prefer to verify the audited code rather than rely on funding history alone.
