Network fingerprint
What this network does to VPN traffic, read from comparing kinds of tests. “Observed” means the measurements are consistent with the behaviour — not proof of intent.

Server ports (plain TCP)100%
Observed behaviour
Server addresses unreachable (IP or port blocking)Share of plain TCP connections to the servers' ports that failed. Measured: 0.0% failed over 2,368 tests.Not observed
TCP transports fail although the port answersTunnel failure rate of TCP transports minus the failure rate of plain TCP connects to the same ports. A gap points at inspection of the traffic, not at blocked addresses. Measured: a gap of 2.2 points over 2,368 tests.Not observed
QUIC/UDP transports fail more often than TCP onesFailure rate of Hysteria2 (QUIC over UDP) minus that of the TCP transports to the same servers. Measured: a gap of 0.0 points over 585 tests.Not observed
Plain DNS over UDP to public resolvers disruptedFailure rate of DNS queries over UDP minus the same queries over TCP to the same public resolvers. Measured: a gap of 0.0 points over 44 tests.Not observed
HTTPS to neutral websites fails without a VPNFailure rate of direct HTTPS requests to well-known neutral sites. Shows whether the network itself works when tunnels fail. Measured: 0.0% failed over 66 tests.Not observed
