Mixed
Results vary across blockchain.info: of 4 URLs tested, 1 is blocked and 3 are disrupted some of the time. The Great Firewall breaks its TLS handshake. 164 tests have been run under this domain since 2012-08-24, the most recent on 2026-07-03.
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://blockchain.info is blocked, https://blockchain.info 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 blockchain.info. 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.
