rthk.hk
Mixed
Results vary across rthk.hk: of 109 URLs tested, 82 are blocked, 24 are disrupted some of the time and 3 have no conclusive recent result. The Great Firewall poisons its DNS, silently drops its packets so requests time out and blocks the connection outright. 3,053 tests have been run under this domain since 2011-03-29, the most recent on 2026-07-26.
The two are filtered by different means — an unencrypted request by the address and keywords it carries in the clear, an encrypted one by the server name in its TLS handshake — so one working while the other does not is normal.

About rthk.hk and the Great Firewall
Results vary across rthk.hk: of 109 URLs tested, 82 are blocked, 24 are disrupted some of the time and 3 have no conclusive recent result. The Great Firewall poisons its DNS, silently drops its packets so requests time out and blocks the connection outright. 3,053 tests have been run under this domain since 2011-03-29, the most recent on 2026-07-26.
Plain HTTP and HTTPS differ here: http://rthk.hk is blocked, https://rthk.hk is intermittent. The two are filtered by different means — an unencrypted request by the address and keywords it carries in the clear, an encrypted one by the server name in its TLS handshake — so one working while the other does not is normal.
A VPN or another circumvention tool routes the request outside mainland China, past the filtering that blocks rthk.hk. GreatFire runs GreatFire VPN; the Analyzer also tests the domains of many VPN and proxy providers, so you can check whether one is reachable before relying on it.
