mpg.de
Mixed
Results vary across mpg.de: of 10 URLs tested, 2 are blocked, 7 load normally and 1 has no conclusive recent result. The Great Firewall resets the connection. 186 tests have been run under this domain since 2012-08-24, the most recent on 2026-08-11.
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://mpg.de is not blocked, https://mpg.de 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 mpg.de. 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.
