Mixed
Results vary across bitcoin.org: of 9 URLs tested, 2 are blocked and 7 load normally. The Great Firewall poisons its DNS and silently drops its packets so requests time out. 408 tests have been run under this domain since 2011-06-03, the most recent on 2026-06-03.
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.

Plain HTTP and HTTPS differ here: http://bitcoin.org is not blocked, https://bitcoin.org is blocked. 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 bitcoin.org. 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.
