On June 04, 2025, 09:21 AM UTC, Psiphon did not appear to work on AS17858 in South Korea.

While the OONI Probe Psiphon test was able to bootstrap Psiphon, it was unable to fetch a webpage from the internet.

This suggests that the Psiphon app may have been blocked on this network.

However, false positives can occur. Please explore the network measurement data below and compare it with other relevant measurements (if they're available).
