abc.com
Mixed
Results vary across abc.com: of 5 URLs tested, 2 are blocked, 2 are disrupted some of the time and 1 has no conclusive recent result. The Great Firewall resets the connection and silently drops its packets so requests time out. 372 tests have been run under this domain since 2011-05-16, the most recent on 2026-08-20.
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://abc.com is blocked, https://abc.com 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 abc.com. 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.
