Psiphon is an open-source circumvention tool combining VPN, SSH and HTTP proxy with domain fronting. It has no public API, so IranBlock does not collect its numbers; OONI's psiphon test, on /networks and /investigate, measures whether it connects from inside Iran. The interactive dashboard at psix.ca shows near-real-time usage by country.
Usage by country is published only on Psiphon's own dashboard. Source: psiphon.ca
